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

We have then:

[tex] v =\frac{d}{t}
[/tex]

Where,

d: distance

t: time

Then, on the other hand we have:

1 hour = 60 minutes

Substituting values we have:

[tex] v = \frac{2\frac{3}{4}}{1\frac{15}{60}} [/tex]

Rewriting we have:

[tex] v= \frac{\frac{11}{4}}{\frac{75}{60}} [/tex]

[tex] v= \frac{\frac{11}{4}}{\frac{5}{4}} [/tex]

[tex] v = \frac{11}{5} [/tex]

Answer:

Ammar hikes [tex] \frac{11}{5} [/tex] miles per hour
