Question 743551:
Danielle drove to a resort 260 miles from her home. She averaged 54 mph for the first part of her trip and 50 mph for the second part. If her total driving time was 5 hours, how long did she travel at each rate? Answer by checkley79(3341) (Show Source):
You can put this solution on YOUR website! D=RT
260=54T+50(5-T)
260=54T+250-50T
260-250=4T
10=4T
T=10/4
T=2.5 HOURS @ 54MPH.
5-2.5=2.5 HOURS @ 50MPH.
PROOF:
260=54*2.5+50*2,5
260=135+125
260=260
