Question 99230: I am having a problem solving this linear equation. A college student drives at 95km/h from home to a park and 70km/h from the park back to home. If the round-trip takes 45 minutes, how long does it take from the park back to home? Answer by checkley71(8403) (Show Source):
You can put this solution on YOUR website! 95(45-T)=70*T
4275-95T=70T
70T+95T=4275
165T=4275
T=4275/165
T=25.909 MINUTES FOR THE RETURN TRIP.
PROOF
95(45-25.909)=70*25.909
95(19.091)=1813.6
1813.6=1813.6
