I need help! Please include an explanation.

Answer 1

Answer: C.
`56\;(2)/(3)` miles per hour

Explanation:

To find the average, we will add together the data values and then divide by the number of values.

➜ We have 50 mph for one hour and 60 mph for two hours, this means that we have one 50 mph value and two 60 mph values since Jon drove 60 mph for two hours instead of one.

`\displaystyle (50+60+60)/(3) =(170)/(3) =\boxed{56\;(2)/(3) \;\;\text{miles per hour}}`
