Answer:

40/10 [4 meters/sec]

Step-by-step explanation:

Watch for what the units are telling us. The number that is being requested

is speed in units of meters/sec. We are given 40 meters and 10 seconds. If we divide 40 meters by 10 seconds (10 meters/10 seconds), we get 4 meters/sec, the correct dimension.

Answer:

Option A

$188$ pi over $15$

Step-by-step explanation:

Step 1

Find the circumference of the tire

$C=\pi D$

where

D is the diameter of the tire

In this problem we have

$D=48\ in$

substitute the value

$C=\pi (48)$

$C=48\pi\ in$

Remember that

$360\°$ subtends the complete circle the arc length $48\pi\ in$

by proportion

Find how far does the rock travel in $94\°$ of rotation

$\frac{48\pi }{360}=\frac{x}{94}\\ \\x=94*48\pi /360\\ \\x=\frac{4,512}{360}\pi$

Simplify

$x=\frac{188}{15}\pi$
