Question 964014: A train travels 80 mi in the same time that a light plane can travel 280 mi. If the speed of the plane is 100 mi/h faster than that of the train, find each of the rates. Answer by josgarithmetic(39623) (Show Source):
You can put this solution on YOUR website! ________________rate____________time____________distance
train___________r________________t_______________U
plane___________r+k______________t_______________V
RT=D rate time distance relationship for rate, time, distance, uniform travel rates rule.
KNOWN:
U=80
V=280
k=100
UNKNOWN:
r, t.
- ------solution formula for r, the rate for the train.
-
Substitute the given values to evaluate r.
