You can put this solution on YOUR website! A car traveled 50 mph between two towns.
If the speed had been 10 mph faster, the trip could have been made in 1 hr. less time.
How far apart are the towns?
:
Let d = dist between towns
:
Write a time equation; time = dist/speed
:
Actual speed time - faster time = 1 hr - = 1
Multiply by 300
6d - 5d = 300
d = 300 mi between towns
:
Check by finding the times
300/50 = 6 hr
300/60 = 5 hrs
