Question

The time it takes to travel a fixed distance varies inversely with the speed traveled. If it takes Patrick 40 minutes to bike to his fishing spot at 9 miles per hour, how long will it take him if he rides at 12 miles per hour?

Answer 1

Answer: 30 minutes

Explanation:

First find the distance that Patrick traveled in that time:

= 40/60 minutes per hour * 9

= 6 miles

If he were travelling at a speed of 12 miles an hour, the amount of time it would take him would be:

= Distance / Speed

= 6 miles / 12 miles per hour

= 0.5 hours

= 0. 5 * 60 mins

= 30 minutes
