Hi I'm a bit confused, why does the time of the bicycle has -2?
I mean how did it became 2x in 60-2x/x isn't it 60-2/x ?
it's actually 60/x - 2 . I made a mistake in labelling that. The time it took the bike to travel is actually 60/x only. To make the equation true, we need -2 because THE MOTORCYCLE TOOK 2 HOURS LESS THAN THE BICYCLE.
