A watusi, a Ubangi, and a Pigmy compare the speeds at which ech can run.
The sum of the speeds of the natives is 30 miles per hour (mph). The Pigmy's
speed plus one-third of the Watusi's speed is 22 miles per hour more that the
Ubangi's sped. Four times the Watusi's speed plus three times the Ublani's
speed minus twice the Pigmys' speed is 12 miles per hour. Find out how fast
each can run. Then, tell what is unfortunate about the Ubangi.
