1. tony runs 6 miles in 49 minutes. how many miles does he run per minute?
2. at keller's bike rentals, it costs $22 to rent a bike for 5 hours. how many dollars does it cost per hour of bike use?

Step-by-step explanation:

6 miles in 49 minutes = x miles in 1 minute

proportion time

   6           x

  =      cross multiply

 49             1

49x = 6 divide both sides by 49

x = 6/49

x = 0.12244 rounds to 0.12 miles per minute <

22 bucks for 5 hrs = x bucks for 1 hr...

 22           x

 =      cross multiply

 5               1

5x = 22...divide both sides by 5

x = 22/5

x = 4.4so its $ 4.40 per hr <===
