Real-Life Math
As a tennis pro, you are in charge of a variety of people who are
in the gym trying to improve their tennis game. "You have to come up with
different strategies and drills that will help the individual," says Tudor
Nita, a tennis pro.
"When you're teaching a number of people, it's
important to keep everyone busy," says Nita. "You use math to figure out the
number of balls needed for a drill, and the combinations of activities they
should use them for."
You have a bucket of 125 tennis balls and 2 players
that you want to set up for practice. Mindy needs to work on her backhand
return. Travis needs to practice his serve.
After they complete the
repetitions, you will want to find out how well they have done. "We are always
working out percentage of shots to figure out how many good shots a player
is making," says Nita.
Situation 1
You count out and
feed Mindy 65 balls to practice her backhand. After she hits the balls, she
counts how many are still on her side of the net. There are 14 balls. What
is her success rate on her backhand?
Situation 2
You
gave the rest of the balls in the bucket to Travis. When he finishes practicing
his serve, he has shot 40 balls over the net. What is his success rate on
his serve?
