Question

Sammy can roll a bowling ball at a rate of 5 miles in 30 seconds. How fast can he

roll it in miles per hour?*

Answer 1

600 mph

Explanation:

Given that,

Distance covered by ball, d = 5 miles

Time taken, t = 30 seconds

1 second = (1/3600) hour

Speed = distance/time

`v=\frac{5\ \text{miles}}{30* (1)/(3600)\ \text{hour}}\\\\v=600\ mph`

So, the speed of the ball is 600 mph.
