Question

Jerry ran 3/4 of a mile in 1/8 of an hour. What was Jerry's rate of speed in miles per hour?

Answer 1

6 miles per hour

Explanation:

we'll set up the problem like this:

3/4 mi = 1/8 hr

now multiply each side by 8:

24/4 mi = 1 hr

simplify:

6 mi = 1 hr

Answer 2

The rate of speed of Jerry in miles per hour is 6 miles per hour

Solution:

Given that, Jerry ran 3/4 of a mile in 1/8 of an hour.

To find: Jerry's rate of speed in miles per hour

The relation between distance and speed is given as:

`\text { distance travelled }=\text { speed } * \text { time taken }`

`\text { In our problem, distance travelled }=(3)/(4) \text { mile and time taken }=(1)/(8) \text { hour }`

`\begin{array}{l}{\rightarrow \text { speed }=((3)/(4))/((1)/(8))} \\\\ {\rightarrow \text { speed }=(3)/(4) * (8)/(1)=6} \\\\ {\rightarrow \text { speed }=6 \text { miles per hour }}\end{array}`

Hence, the speed of Jerry is 6 mile per hour.
