Question

Need help pppppleaseThe 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?

A.
m = 4.5t

B.
m = 9.5t

C.
m = 17t

D.
m = 21t

Answer 1

b. 19/2 =9.5
to get this you put it in the direct variation equation. Y=kx. k is the rate. the rate we have now is every two hours we travel 19 miles. we want every 1 hour to fit the equation. thus 19/2
