Hello ! I'm happy to help
the answer all revolves around this simple formula:
speed= distance/time
since you were driving for 1/4 of an hour that's 15 minutes
and we already know that you traveled 15 miles
so the speed would equal 15 miles every 15 minutes
if you want to find the total distance travelled is 15x15 =225
10*8=80
3*8=24
80-24=56
You would save $56.00 in 8 weeks
Do it on a scientific calculator
W=4 that the answer !!!!!
