Question

Ammar hikes 2 3/4 miles of nature trail in 1 hour and 15 minutes. How many miles of trail does Ammar hike per hour?

Answer 1

`2(3)/(4)=(11)/(4) \\\\ 1h \ 15min=60 min +15min\to\boxed{75min} \\\\ (11)/(4)......75min \\\\ x..........60min \\\\ x=((11)/(4)*60)/(75) \\\\ x=(11*15)/(75) \\\\ \boxed{x=(11)/(5)miles}`

Answer 2

For this case, what we should do is find Ammar's speed.

We have then:

`image`

Where,

d: distance

t: time

Then, on the other hand we have:

1 hour = 60 minutes

Substituting values we have:

`v = (2(3)/(4))/(1(15)/(60))`

Rewriting we have:

`v= ((11)/(4))/((75)/(60))`

`v= ((11)/(4))/((5)/(4))`

`v = (11)/(5)`

Answer:

Ammar hikes
`(11)/(5)` miles per hour
