Question

A turtle moves $i$ inches in $m$ minutes. At this rate, how many feet can it move in $h$ hours?

• A. $\frac{5hi}{m}$
• B. $\frac{60hi}{m}$
• C. $\frac{hi}{12m}$
• D. $\frac{5m}{hi}$

Answer 1

The correct option is A $\frac{5hi}{m}$

The turtle moves $i$ inches in $m$ minutes.

We are asked to find out how many feet will it move in $h$ hours.

Here, we will have to convert feet into inches and hours into minutes.

Let $x$ be the distance in feet covered by the turtle.

$\therefore$ Feet $=12x$ inches

Also, $h$ hours $=60h$ minutes.

To find out the distance traveled by the turtle, we need to form proportions.

$\therefore \frac{i}{m}=\frac{12x}{60h}$

$\Rightarrow x=\frac{60h.i}{12m}=\frac{5h.i}{m}$
