## What is the formula for calculating time?

Formula 2.

Another simple technique to calculate the duration between two times in Excel is using the TEXT function: Calculate hours between two times: =TEXT(B2-A2, “h”) Return hours and minutes between 2 times: =TEXT(B2-A2, “h:mm”) Return hours, minutes and seconds between 2 times: =TEXT(B2-A2, “h:mm:ss”).

## What are four factors that affect braking distance?

Braking distancepoor road and weather conditions, such as wet or icy roads.poor vehicle conditions, such as worn brakes or worn tyres.a greater speed.the car’s mass – more mass means a greater braking distance.

## What are the six factors that affect your braking distance?

Factors that affect braking distance include “driver ability, speed, vehicle condition, roadway surface, hills, and weight of vehicle’s load”. You can control speed, ability, and the weight of the vehicle’s load.

## How can I improve my driving reflexes?

Seven top tips to improve your reflexesPick a sport, any sport – and practise. What exactly do you want to improve your reflexes for? … Chill out. Your reaction time is always going to be slower if you’re too tense. … Eat a lot of spinach and eggs. … Play more video games (no, really) … Use your loose change. … Playing ball. … Make sure you get enough sleep.

## What is stopping distance in physics?

stopping distance = thinking distance + braking distance. This is when: thinking distance is the distance a vehicle travels in the time it takes for the driver to apply the brakes after realising they need to stop. braking distance is the distance a vehicle travels in the time after the driver has applied the brake.

## How do you calculate thinking distance?

It is important to note that the thinking distance is proportional to the starting speed. This is because the reaction time is taken as a constant, and distance = speed × time.

## What is a good braking distance?

Average Stopping Distance by CategoryCategoryAverage dry braking 60-0 mph, ft.Large luxury cars138Large SUVs139Full-sized pickup trucks142Average of all tested vehicles13214 more rows•Oct 30, 2019

## How do you calculate safe speed?

To determine a safe speed, you must know stopping distances and how to factor in sight distance and reaction time.Sight Distance. Sight distance is the distance from which you can see and identify a hazard, not necessarily the total distance you can see. … Reaction Time. … Reaction Time Distance.

## What can you do to reduce your reaction distance?

The reaction distance can be decreased by Anticipation of hazards.

## What is the total stopping distance is the distance?

Total Stopping Distance is the sum of the perception distance, reaction distance and braking distance. Once a driver perceives a need to slow or stop, a small amount of time passes. The time it takes to react and come into the correct braking position is the reaction distance.

## What is reaction distance in driving?

Reaction distance is how far your car travels in the time it takes the driver to react to a hazard and step on the brake. Braking distance is how far your car travels from the time the brakes are applied until it comes to a complete stop.

## What affects the braking distance of a vehicle?

The braking distance also depends on the speed of the car, the mass of the car, how worn the brakes and tyres are, and the road surface. A fast, heavy car with worn tyres and brakes, on a wet or icy road will have a large braking distance.

## How do u calculate distance?

distance = speed × time. time = distance ÷ speed.

## How do you calculate brake distance?

Expressed in the formula: (speed ÷ 10) × (speed ÷ 10) + (speed ÷ 10 × 3). For my standard example at 100 km/h, the stopping distance under normal braking is 130 metres.

## How do you use the 4 second rule?

You should apply the four-second rule when it’s wet, frosty or when you are towing a trailer. The four-second rule means that you leave four seconds between you and the vehicle in front. It gives you more time to react and more time to stop.
