Answer:
The car was 132 feet far before the driver reacts to an obstacle.
Step-by-step explanation:
Given,
The speed of car = 60 miles per hour,
Also, time taken by the car to reacting the obstacle = 1.5 seconds = [tex]\frac{1.5}{3600}=\frac{1}{2400}\text{ hours}[/tex],
( 1 hour = 3600 seconds )
We know that,
Distance = Speed × Time,
Hence, the distance of car from the obstacle before reacting the obstacle
[tex]= 60\times \frac{1}{2400}[/tex]
[tex]=\frac{60}{2400}[/tex]
[tex]=\frac{1}{40}\text{ miles}[/tex]
Since, 1 mile = 5280 feet
[tex]\implies \frac{1}{40}\text{ miles }=\frac{5280}{40}=132\text{ feet}[/tex]
Therefore, the car would 132 feet far from the obstacle.
