You can put this solution on YOUR website! A car and a van leave from the same point, at the same time, on the same path.
The van travels 48mph, car travels 40mph.
The van stops after driving 35 miles.
How long till the car catches up to the van?
:
Let w = time the van waits
:
write a time equation, time = dist/speed
:
w = -
Multiply by a common denominator of 240, results
240w = 6(35) - 5(35)
240w = 210 - 175
240w = 35
w = 35/240 * 60 (to get time in minutes)
w = 8.75 minutes
