a 140 lb student burns 5.4 calories a minute after 60 minutes how much calories were burned?
5.4 * 60
To find out how many calories were burned after 60 minutes, we need to multiply the calories burned per minute by the total number of minutes.
Given:
Weight of the student = 140 lb
Calories burned per minute = 5.4
Step 1: Convert the weight from pounds to kilograms.
1 lb is approximately equal to 0.45 kg.
Weight in kg = 140 lb * 0.45 kg/lb
Weight in kg = 63 kg (Approximately)
Step 2: Calculate the total calories burned after 60 minutes.
Calories burned = Calories burned per minute * Total minutes
Calories burned = 5.4 cal/minute * 60 minutes
Calories burned = 324 calories
Therefore, the student burned approximately 324 calories after 60 minutes.
Please note that this is a rough estimate as the number of calories burned can vary based on individual metabolism and activity level.
