Asked/ Problem: How many kilometers did

Answer 1

the number of kilometers hiked in all is
`(29)/(21)`

Explanation:

The computation of the number of kilometers hiked in all is shown below:

= Erwin + Jericho

`= (5)/(7) + (2)/(3)\\\\= (15 + 14)/(21) \\\\= (29)/(21)`

Hence, the number of kilometers hiked in all is
`(29)/(21)`
