Question 990075: This morning a train left the station heading directly north at 50 miles per hour. Two hours later a bus left the same station heading directly south at 60 miles per hour. How long after the bus leave the station will the bus and the train be 650 miles apart? Answer by macston(5194) (Show Source):
You can put this solution on YOUR website! .
Distance apart when bus leaves=(2hrs)(50mph)=100mi
.
When both are moving, the bus and train separate at 50mph+60mph=110mph
.
When the bus starts, they must travel 650mi-100mi=550 miles
to be 650 miles apart. To travel 550 miles at 110mph:
(550 miles)/(110 mi/hr)=5 hours
.
ANSWER: They will be 650 miles apart 5 hours after the bus leaves.
