A freight train left Washington and traveled south.

Question

A freight train left Washington and

traveled south. A diesel train left six hours

later traveling at 85 km/h in an effort to

catch up to the freight train. After

traveling for 11 hours the diesel train

finally caught up. What was the freight

train's average speed?

Answer 1

The freight train travelled for 17 hours (11 + 6)

d = r * t

(11)(85) = (17)(r)

Can you solve for r and answer?
