Question

1. If a car is traveling 90 mi/hr, how many feet will the car travel in 1 sec? In 5 sec?

Hints: 5280 ft = 1 mi
60 sec = 1 min
60 min = 1 hour

Answer 1

The car travel 660 feet

Step-by-step explanation:

First convert the Speed into Feet/sec

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 :

`Speed =(distance)/(time)`

`Speed =(90mi)/(1hr)`... given

`Speed =(475200 ft)/(3600sec)`

Speed = 132 ft/sec

Now, time = 5 sec

`Speed =(distance)/(time)`

`distance =speed* time`

`distance = 132ft/sec* 5sec`

Distance = 660 feet
