Question

The number of miles Melody rides her bicycle, m, varies directly with the amount of time spent riding the bike, t. When Melody bikes for 1.5 h, she travels 10.5 mi. Which equation shows this direct linear variation?
A.

m = 7t


B.

m = 7.5t



C.

m = 12t



D.

m = 15.75t

i think its B

Answer 1

It is A.

"When Melody bikes for 1.5 h, she travels 10.5 mi.", therefore her speed is 10.5/1.5 = 7 mi/hr. So the right equation is m = 7t.
