Question 596621: two drivers start driving toward each other in cities that are 540 miles apart. they pass each other when the slower driver has traveled 240 miles. if the faster driver is traveling 15 miles per hour faster than the slower driver, find out how fast each driver is going.

You can put this solution on YOUR website! two drivers start driving toward each other in cities that are 540 miles apart. they pass each other when the slower driver has traveled 240 miles. if the faster driver is traveling 15 miles per hour faster than the slower driver, find out how fast each driver is going.
**
let x=speed of slower driver traveling 240 miles
x+15 =speed of faster driver traveling 300 miles
When they met, both drivers had been traveling for the same amount of time
travel time = distance/speed
240/x=300/x+15
300x=240x+240*15
300x=240x+3600
60x=3600
x=3600/60=60
x+15=75
ans:
speed of slower driver=60 mph
speed of faster driver=75 mph
