Question

In 4 hours, you hike 10 miles. Which unit rate describes your speed on the hike?

Answer 1

2.5 mph is the answer I believe!

Answer 2

`2\:(1)/(2)\:or\: 2.5 mph`

Miles per hour

Explanation:

Since you have a rate is given by:

`V_(Average)=(\Delta s)/(\Delta t)`

The unit on the numerator, is miles and on the denominator is hours. This unit rate miles per hour then it is used.

Back to the calculations:

`V_(Average)=(\Delta s)/(\Delta t)\Rightarrow V_(Average)=(10-0)/(4-0)=2\:(1)/(2)\:or\: 2.5 mph\:`
