Question

Ash has a walking and cycling routine. For every minute she walks, she burns 20 calories. How many calories will she burn in 30 minutes of walking?

a) 300 calories
b) 400 calories
c) 500 calories
d) 600 calories

Answer 1

Ash will burn 600 calories during 30 minutes of walking, calculated by multiplying the rate of 20 calories per minute by the walking duration.

Step-by-step explanation:

To calculate how many calories Ash will burn in 30 minutes of walking, we can use the information provided that she burns 20 calories per minute. We need to multiply the number of minutes by the calories burned per minute as follows:

1. Identify the calories burned per minute: 20 calories.
2. Multiply this rate by the total walking time in minutes: 30 minutes.
3. Perform the calculation: 20 calories/minute × 30 minutes = 600 calories.

Therefore, the answer is (d) 600 calories.
