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}

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

We have then:

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
