Answer:
The car travel 660 feet
Explanation:
First convert the Speed into <u>Feet/sec</u>
Speed of the car = 90 mi/hr
1 mi = 5280 ft
In 90 miles = 90 x 5280 = 475,200 feet
1 hr = 60 min
1 min = 60 sec
So ,
1 hr = 60 x 60 sec = 3600 sec
The speed is defined as the distance traveled by the object in unit time. The formula of speed is :

... given

Speed = 132 ft/sec
Now, time = 5 sec



Distance = 660 feet
