1. An airplane flies with a constant speed of 560 miles per hour. How far can it travel in 4 hours? 2. Sarah rides her bike with a constant speed of 12 miles per hour. How far can she travel in
3 1/2 hours?

2240 miles.   42 miles

Step-by-step explanation:

This is so easy. For the first question you know that for each hour the plane goes 560 miles. All you have to do is times four with 560 and you get 2240 miles. Likewise, for each hour she rides her bike 12 miles. Using the same logic I times 12 with 3.5 and I got 42 miles.

the answer would be c:   ax + b = ax + c
