If she biked for x hours, she drove by car for 4-x hours.

since distance = speed * time, add up the distances:

17x + 12(4-x) = 56

x = 1.6

check:

17*1.6 = 27.2

12*2.4 = 28.8

total: 56 miles.

What junker of a car travels 12 mph?

That must have been a mopad or something because what kind of motorcycle goes that slow?
