Question

Charles is on a 8 1/2 mile bike ride. He stops for a rest after he’s gone 5 2/5 miles. How much farther does he still have to go?

Answer 1

31/10 or 3 1/10 more miles.

Explanation:

=

(17 × 5) - (27 × 2)

2 × 5

Answer 2

`3(1)/(10)` miles

Explanation:

The total distance of Charles bike ride is =
`8(1)/(2)` miles

He has covered the distance =
`5(2)/(5)` miles

We will subtract his covered distance from total distance.

He still have to go =
`8(1)/(2)` -
`5(2)/(5)`

=
`(17)/(2)` -
`(27)/(5)`

=
`(85-54)/(10)`

=
`(31)/(10)`

=
`3(1)/(10)` miles

He still have to go
`3(1)/(10)` miles
