Question

Radhika uses 8 hours 15 minutes throughout the week for her exercises. She swims for 3 hours 45 minutes. The rest of the time she jogs. For how long does she jog every week

Answer 1

To find out how long Radhika jogs each week, subtract the time she spends swimming from her total exercise time. She jogs for 4 hours and 30 minutes each week.

Step-by-step explanation:

The total exercise time Radhika uses throughout the week is 8 hours and 15 minutes. Out of this, she swims for 3 hours and 45 minutes. To find out how long she jogs, we need to subtract the time she spends swimming from the total exercise time.

Step 1: Convert the time to minutes to make the subtraction easier. 1 hour = 60 minutes.

So, Radhika's total exercise time in minutes is 8 hours × 60 minutes/hour + 15 minutes = 495 minutes.

The time she spends swimming is 3 hours × 60 minutes/hour + 45 minutes = 225 minutes.

Step 2: Subtract the swimming time from the total exercise time. 495 minutes - 225 minutes = 270 minutes.

Step 3: Convert the jogging time back to hours and minutes. 270 minutes ÷ 60 minutes/hour = 4 hours with 30 minutes remaining.

So, Radhika jogs for 4 hours and 30 minutes each week.
