Question

An athlete spends 75 minutes a day on a cardio workout and 60 minutes a day on strength workout. The athlete does the cardio workout 20 days in a month, and the strength workout 25 days in the month. Which equation could be used to find n, the total number of minutes the athlete spends working out in the month?

Answer 1

Answer: n = (75 × 20) + (60 × 25)

Explanation:

Minutes spent a day on cardio workout = 75 minutes

Minutes spent per day on strength workout = 60 minutes

Since the athlete does the cardio workout 20 days in a month, and the strength workout 25 days in the month. Therefore, the equation that could be used to find n, the total number of minutes the athlete spends working out in the month will be:

n = (75 × 20) + (60 × 25)

Therefore, the equation is:

n = (75 × 20) + (60 × 25)

Total minutes used will be:

n = (75 × 20) + (60 × 25)

n = 1500 + 1500

n = 3000 minutes

Since 60 minutes = 1 hour

n = 3000/60

n = 50 hours
