How would you set up an equation to represent the situation?

Think that every time he runs around the track, he travels an additional 1/4 mile.

9/10 - 1/4 everytime?

btaylor · Answer

kinda. I would set it up as: $$\frac{1}{4} \times t = \frac{9}{10}$$
Could you solve that?

anonymous · Answer

so i would divide 1/4 on both sides?

btaylor · Answer

yes, which is the same as multiplying by 4.

anonymous · Answer

it would be 3 3/5? thats what i got
