Question

If Kayla ran 9/10 mile yesterday today she ran 8/9 the distance she ran yesterday which day did Kayla run more miles? Explain your reasoning

Answer 1

Kayla ran longer miles yesterday than today

Explanation:

Distance Kayla ran yesterday be x

Then x =
`(9)/(10)` mile

That is x = 0.9 miles

The Distance she ran today be y

Then y =
`(8)/(9)` of the distance she ran yesterday

So the distance Kayla ran today

=
`(8)/(9)`
`* \text { the distance she ran yesterday }`

On substituting the value

y =
`(8)/(9) *(9)/(10)`

y =
`(8)/(10)`

y = 0.8 miles

x is greater than y

0.9 > 0.8
