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?

Answer 1

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 <===
