A man travels a total of 4.2 miles each day to and from work.
The traveling consumes 72 minutes each day.
How many hours would he save in 129 working days if he moved to another
residence so that he would travel only 1.7 miles each day assuming he traveled at the same rate?
:
Find no. of minutes (m) required per day traveling only 1.7 mi
m%2F72 = 1.7%2F4.2
cross multiply
4.2m = 72 * 1.7
4.2m = 122.4
m = 122.5%2F4.2
m = 29 minutes per day
:
Find the no. of hrs save in 129 days
%28129%2872-29%29%29%2F60 = 92.45 hrs
