Question

Your record bicycle pace along a favorite trail is 16 mph. On a recent ride, you traveled the 25 mile route in a time of 90 minutes. What was your average speed? Did it break your record pace?

Answer 1

Remember that d = rt or distance = rate times time.  You want your answer in miles per hour so convert 90 minutes to 1.5 hours.  Now plug in your values:
25mi = r*1.5hrs.
r = 25/1.5 = 16.667mph.

This is greater than 16mph so you did break your record pace.

You did break your pace. You were able to travle about .7 miles per hour faster.

Step-by-step explanation:

Speed: Distance/time

Speed: 25/90

Speed: 16.6667 miles per hour
