Speed used by Emily from home to post office is:
speed=(distance)/(time)
distance=3/4 miles
time=8:29:30-8:25=4 min 30 sec=4.5 min
thus speed=(0.75)/4.5=1/6 mile/min
The remaining distance from Post office to school:
3.42-0.75=2.67 miles
time taken to reach to school assuming that Emily will move with the same speed is:
time=2.67/(1/6)=16.02 min=16 min 1.2 seconds
time Emily will reach school is:
8:29:30+0:16:1.2
=8:45:31 a.m
This means that she will reach on time
