Question

One lap around the schools track is 1/4 mile. It takes Alex 1/12 hour to run one lap. What is Alex’s unit rate, in miles per hour, around the track?

Answer 1

Step-by-step explanation:

when he we know that

speed = distance/time

=(1/4)/(1/12)

=12/4=3 miles per hour

Answer 2

Alex’s unit rate, in miles per hour, around the track is 3 miles per hour

Solution:

One lap around the school track = $\frac{1}{4}$ miles

Time taken to cover this one lap = $\frac{1}{12}$ hour

The relation between speed and distance and time is given as:

$\text { speed }=\frac{\text { distance travelled }}{\text { time taken }}$

According to the given question, Speed of Alex is calculated as,

$\text {speed}=\frac{\frac{1}{4}}{\frac{1}{12}}$

$= \frac{12}{4}$

= 3 miles/hour

So, Alex's unit rate in miles per hour around the track = 3 miles/hour
