You can put this solution on YOUR website! a disabled freight train is traveling toward a station 140 km away at a speed of 32 km/h.
another train, traveling 80 km/h, leaves the station to pick up the freight.
when will the two trains meet?
:
Let t = travel time for the two trains to meet
:
When the two trains meet, they will have traveled a total of 140 km
Write a distance equation, dist = speed * time
:
32t + 80t = 140
112t = 140
t = 140/112
t = 1.25 hrs or 1 hr, 15 min
