You can put this solution on YOUR website! s = d/t
d = st
---
d = 55*1.5
d = 82.5 miles to work
---
spent per mile:
(1/30 gallon/miles) * (3.45 dollars/gallon) = 0.115
---
total spent one-way:
(82.5 miles) * (1/30 gallon/miles) * (3.45 dollars/gallon) = 9.4875
---
answer:
expense per mile = $0.115
expense one-way to work = $9.49
