Joan is going on a bike trip. She plans to ride 9 miles in 45 minutes. At what rate mi/min must she travel?

just divide the miles by the minutes

Joan is going on a bike trip. She plans to ride 9 miles in 45 min. At what rate mi/min must she travel?

A cheetah can run at the speed of 60 mph. How far can it run in 0.25 hours?

A garden snail can travel 0.03 mph. How long would it take to travel 0.75 miles?

A cheetah can run at the speed of 60 mph. How far can it run in 0.25 hours?

To find the rate at which Joan must travel in miles per minute, we need to divide the distance she plans to ride by the time it will take her.

Rate (mi/min) = Distance (miles) / Time (minutes)

In this case, the distance Joan plans to ride is 9 miles, and the time it will take her is 45 minutes.

Rate (mi/min) = 9 miles / 45 minutes

To calculate this, we simply divide 9 by 45.

Rate (mi/min) = 0.2 miles per minute

Therefore, Joan must travel at a rate of 0.2 miles per minute to cover the distance of 9 miles in 45 minutes.
