Answer:

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