Question

Chen bikes 2 1/2 miles in 5/12 hour. What is Chen's unit rate in miles per hour?

Answer 1

Answer: 6 miles per hour

Step-by-step explanation:

if you divide them both by 5, you would get 1/2 miles in 1/12 hour, so you multiply it by 12, 6 miles in 1 hour so his unit rate would be 6 mph

Answer 2

Answer:

6 miles per hour

Step-by-step explanation:

Distance traveled, d = 2 1/2 miles = 5 / 2 miles

time taken, t = 5 / 12 hour

Speed is defined as the ratio of distance traveled to the time taken.

$Speed = \frac{distance}{time}$

$Speed = \frac{\frac{5}{2}}{\frac{5}{12}}$

speed = 6 miles per hhour

Thus, the unit rate of Chen is 6 miles per hour.
