Question

It is estimated that a driver takes, on average, 1.5 seconds from seeing on obstacle to react by applying the brakes to stop or swerving. How far will a car, moving at 26 miles per hour in a residential neighborhood, travel (in feet) before a driver reacts to an obtacle? (round distance to one decimal place) feet

Answer 1

Answer
Answer:
The car was 132 feet far before the driver reacts to an obstacle.
Explanation:
Given,
The speed of car = 60 miles per hour,
Also, time taken by the car to reacting the
obstacle =1.5 seconds = 3600 = 2100 hours
(1 hour = 3600 seconds )
We know that,
Distance = Speed × Time,
Hence, the distance of car from the obstacle before reacting the obstacle
= 60 × 2100
60
2400
# miles
Since, 1 mile = 5280 feet
= # miles = $280 = 132 feet
Therefore, the car would 132 feet far from the obstacle.
