Question 719502: two cars leave town at the same time going in the same direction on the same road. One travels 30 mi/h and the other travels 46 mi/h. If they both start at 2:00 pm, when will they be 76 miles apart? Answer by graphmatics(170) (Show Source):
You can put this solution on YOUR website! Let t be the time in hours that the 2 cars travel. Then at the time the cars are 76 miles apart the cars will have traveled 46*t and 30*t. If they are 76 miles apart then
46t-30t=76
So
16*t=76
t=76/16
t=4.75
So it takes 4.75 hours for the cars to be 76 miles apart. .75% of an hour is 45 minutes, so the time they will be 76 miles apart is 6:45.
