Answer :
[tex]s=m \ miles\\
t=h \ hours \ 45 \ min=h+0.75 \ hours\\
v=\frac{s}{t}\\
v=\frac{m}{h+0.75} =\frac{m}{h+\frac{3}{4}} \Rightarrow A

Speed = (distance covered) / (time to cover the distance).
Time = 'h' hours and 45 minutes.
45 minutes is 3/4 of an hour. (or 0.75 hour)
Total time is (h + 0.75) hours.
Speed = 'm' / (h + 0.75)
That's choice-'a'.
Time = 'h' hours and 45 minutes.
45 minutes is 3/4 of an hour. (or 0.75 hour)
