Question

You are driving down the road at 30 mph (miles per hour) when you see the traffic light change to red. The red light is 300 feet from you. How much time would it take you to stop?

Answer 1

It will take me 0.49seconds for me to stop.

Step-by-step explanation:

Speed is defined as the change in distance of a body with respect to time.

Speed = Distance/Time

Given speed = 30miles per hour

Distance = 300feet

Converting 300feet to miles

If 1 foot = 0.000189 mile

300feet = (300×0.000189)mile

300feet = 0.245mile

Time taken = Distance/speed

Time taken = 0.245/30

Time taken = 0.00819hour

Time taken = 0.49seconds
