Question 280688: 50 hours after a ship sailed new york, a plane left at the same location and traveled the same direction. the plane traveled 400 kmh. if the plane over took the ship in 6 hours, how fast was the ship? Answer by oberobic(2304) (Show Source):
You can put this solution on YOUR website! This problem uses the distance equation: d = rt.
.
Ship r = unknown
t = 56 = 50 hrs head start + 6 hours it took the plan to catch up
d = 2400 km because the plane flew for 6 hours at 400 kmh to catch up
56r = 2400
.
d = rt
r = d/t
.
r = 2400 km/56 hr = 42.8571 kmh = speed of the ship
.
Done.
