  • Time taken=10:00-9:15=0:45 h=3/4h=0.7h
  • Distance=2.5mi

Speed=


\\ \rm\Rrightarrow Distance/Time


\\ \rm\Rrightarrow 2.5/0.7


\\ \rm\Rrightarrow 3.5mph

Answer:

3.3 miles per hour. this is because speed is equal to distance travelled divided by time taken. so you calculate how many minutes he spent that is from 9:15 to 10:00 . since you are calculating in miles per hour, you convert the minutes to hours and do the working according to the formula
