Question

• 1 hour = 60 minutes
• 1 kilometer = 1000 meters
• 1 mile = 1.6 kilometers
Calvin biked 24 miles in 2 hours. What is his approximate
average speed in meters per minute?

Answer 1

1 mile = 1.6 kilometers so 24*1.6 = 38.4
24 miles = 38.4 kilometers

1 kilometer = 1000 meters so 38.4*1000 = 38,400 meters
38.4 kilometers = 38,400 meters

1 hour = 60 minutes so 2*60 = 120
2 hours = 120 minutes

To calculate meters per minute, divide.
38,400 / 120 = 320

So that means that Calvin's approximate speed is 320 meters per minute.
