Question

a car travels 100 meters in 5 seconds. what is the speed of the car? speed = distance over time; 1 mile = 1609 meters 8.9 miles per hour 16 miles per hour 20 miles per hour 44.7 miles per hour

Answer 1

20 meters per second so 44.7 MPH

Answer 2

Speed, v = 44.7 miles/hour

Explanation:

Given that,

Distance covered by the car, d = 100 meters

1 meter = 0.000621371 miles

100 meter = 0.0621371 miles

Time taken by the car, t = 5 seconds = 0.00138889 hours

The speed of the car is given by :

`v=(d)/(t)`

`v=(0.0621371\ miles)/(0.00138889\ hour)`

v = 44.7 miles/hour

So, the speed of the car is 44.7 miles/hour. Hence, this is the required solution.
