Question

Thanks guys for helping me guys question 6

Answer 1

So, doing a guess and check,

Liza's house.

From Liza's house to the Park it is 5
`(1)/(2)` miles.

From the Park to the Library it is also 5
`(1)/(2)` miles.

From the Library to Dan it is 4 miles.

From Dan it is 3 miles back to Liza's house.

So you must add all those together,

5
`(1)/(2)`+5
`(1)/(2)`+4+3

We got lucky because 5
`(1)/(2)`+5
`(1)/(2)` have common denominators.

So,

5
`(1)/(2)`
+
5
`(1)/(2)`

=11 (
`(1)/(2)`+
`(1)/(2)`=1, so 5+5+1)

So that is 11, then,

11+4+3=18

18 miles total.

This is your route. From Liza's house to the Park, then Library, then Dan's, then back to Liza's house.
