Question

The number of miles Abigail’s boat travels, m, varies directly with the amount of time Abigail spends boating, t. If she spends 2 h in her boat, she travels 19 mi. Which direct linear variation equation models the information?

Answer 1

Hello, Tennant17!

The model for direct variation is y=kx where k is a constant.
In this case, y is m and x is t.
So the equation is m=kt
Plug in the values of m and t to find k.

19= k * 2
Solve for k
k= 19/2
k= 9.5

Plug k back into the equation.

m=9.5t

So the answer is:
B. m=9.5t

Hope this helps :)
