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

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

We have then:

\(v =\frac{d}{t}
\)

Where,

d: distance

t: time

Then, on the other hand we have:

1 hour = 60 minutes

Substituting values we have:

\(v = \frac{2\frac{3}{4}}{1\frac{15}{60}}\)

Rewriting we have:

\(v= \frac{\frac{11}{4}}{\frac{75}{60}}\)

\(v= \frac{\frac{11}{4}}{\frac{5}{4}}\)

\(v = \frac{11}{5}\)

Answer:

Ammar hikes \(\frac{11}{5}\) miles per hour
