Question

A boy rolls a bowling ball at a speed of 2 mph it takes 10 seconds to get to the pins how long is the alley?

Answer 1

Answer:

the speed of the ball is

2mph

= 2 m / (60x60) s

=2/3600 m/s

=5.56 x 10^-4 m/s

The alley is

(10 x 5.56x 10^-4) m long

=5.56 x 10^-3 m long.

Hope it helps!

Answer 2

Answer:

The answer is 8.88888 m

Explanation:

We know that,

s = v x t

So, v = 2 mph = 3200 meter/h

Also, t = 10 sec = $\frac{1}{360} h$

So, length of the bowling alley = $3200 * \frac{1}{360} = 8.88m$
