The badminton coach has planned the training sessions such that the ratio of warm up: play: cool down is 10% : 80% : 10%. If he wants to conduct a training of 90 minutes. How long should each activity be done?

Correct Answer

Given: Total training time = 90 minutes Ratio (Warm up : Play : Cool down) = 10% : 80% : 10%

Calculation: Warm up: 10% of 90 minutes = 0.10×900.10 \times 90 = 9 minutes

Play: 80% of 90 minutes = 0.80×900.80 \times 90 = 72 minutes

Cool down: 10% of 90 minutes = 0.10×900.10 \times 90 = 9 minutes

Answer: Warm up: 9 minutes Play: 72 minutes Cool down: 9 minutes

Explanation

The chapter shows how to find percentages of quantities. Each percentage is applied to the total time of 90 minutes.

Solution Steps

  1. Warm up = 10% of 90 minutes = 0.10×900.10 \times 90 = 9 minutes

  2. Play = 80% of 90 minutes = 0.80×900.80 \times 90 = 72 minutes

  3. Cool down = 10% of 90 minutes = 0.10×900.10 \times 90 = 9 minutes
