Question

A charter bus travels 225 miles in

4.5 hours. Assume the
distance traveled is directly
proportional to the time spent.
Write a direct variation equation.

A) x + 50 = y

B) y + 50x = 0

C) x= - 50 y

D) y = 50x

Answer 1

D because y (time spent) = 50 × x (distance travelled)

225÷4.5=50

x÷y=50
