You can put this solution on YOUR website!
r, rate or speed for the motorcycle.
car is then -30+2r.
time passage was 2 hours.

RT=D, typical travel rates rule.

CAR is faster according to question's implication.
highlight%28%282r-30%29%2A2-r%2A2=20%29

Do the steps.
The car goes 50 mph and motorcycle goes 40 mph.
