Write an equation to model this situation. Then complete the input-output table below; and graph the equation on the coordinate plane provided. If two quantities x and y are directly proportional to one another, (meaning if x is doubled, so is y; if x is tripled, so is y), they show direct variation.

Bond [772]

Answer:

A. 10.4 mph

Step-by-step explanation:

26÷2.5=10.4

Double checking your answer:

If she does 10.4 miles in an hour, she can get 20.8 in two hours

then you add half of how much she can go in an hour which is 5.2 (10.4÷2)

you add it together, and you will get 26 miles in total

(20.8+5.2=26)
