Answer:
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
