Answer:

Speed, v = 44.7 miles/hour

Step-by-step 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 :

[tex]v=\dfrac{d}{t}[/tex]

[tex]v=\dfrac{0.0621371\ miles}{0.00138889\ hour}[/tex]

v = 44.7 miles/hour

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