put this solution on YOUR website! moving van - rate: 35 mi/hr time: t hr distance traveled: 35t mi
car - rate: 50 mi/hr time: (t - .75) hr dist traveled: 50*(t - .75)mi
When they meet, the distance each has travelled will be the same

hr (note: this is the time expired from when
the van left until it meets the car)

hr This is the time expired from when the car left

check:

mi
and

mi
OK
