12. The number of miles, y, traveled varies directly as time, x. If a group of tubers floating down the river traveled 9 miles

in two hours, how far would they travel in 5 hours? Write and solve a direct variation equation for this situation

y= 9/2x; x=10/9

y=2/9x; x=22.5

y=2/9x; y=10/9

Oy=9/2; y=22.5
