Question

Zach ran t times around the track at school, which is one-fourth mile. He ran a total of nine-tenths mile. Solve for t.

A) 4 4/9
B) 5/18
C) 3 3/5
D) 9/40

Answer 1

each track is one-fourth mile(1/4), if he ran nine-tenths mile (9/10). 
divide total of ran length by length of each track.
(9/10)/(1/4)=36/10=18/5, and you can write it as 3(3/5)
