Question 602265: On route to the school camp, the bus travelled at 80km/h for a certain period of time t and at 100km/h for twice this period of time. If the total distance covered was 140km, for how long did the bus travel at each speed? Answer by ankor@dixie-net.com(22740) (Show Source):
You can put this solution on YOUR website! the bus travelled at 80km/h for a certain period of time t and at 100km/h for twice this period of time.
If the total distance covered was 140km, for how long did the bus travel at each speed?
:
write a distance equation; dist = speed * time
:
80t + 100(2t) = 140
find t
