Since Raksha is driving at 40MPH, when she leaves Fulbeck, that means she will cover the of distance of 10 miles from Fulbeck to Granby in:
10/40=1/4 of an hour or 15 minutes, which would be 10:15 hours.
But, she needs to cover the distance from Granby to Horton in 10:35-10:15=20 minutes.
So to travel 18 from Granby to Horton in 20 minutes, she must average:
18 miles divided by 20/60=1/3 of an hour, or
18/(1/3)=18 X 3=54MPH-her averge speed to drive from Granby to Horton.
