Question 213179: Two bicyclists are riding toward each
other, and each has an average speed of
10.0 km/h. When their bikes are 20.0
km apart, a pesky fly begins flying from
one wheel to the other at a steady speed
of 30.0 km/h. When the fly gets to the
wheel, it abruptly turns around and flies
back to touch the first wheel, then turns
around and keeps repeating the backand-
forth trip until the bikes meet, and
the fly meets an unfortunate end.
How many kilometers did the fly travel in its total back-and-forth trips?

How many kilometers did the fly travel in its total back-and-forth trips?
--------------
Going toward each other, their speeds are added, = 20 kph.
It will take them 1 hour to cover the 20 km distance.
The fly flies 30 kph for 1 hour, = 30 kms
