Question

Ruby is taking a road trip to see her parents. She drives 114 hours which covers 18 of her trip. How many hours will it take her to complete her trip?

Answer 1

Answer: It will take 10 hours.

Explanation:

Given: Distance traveled by Ruby in
`1\frac14` hours =
`(1)/(8)` of Total trip.

i.e. Time taken to complete
`(1)/(8)` of Total trip=
`1\frac14` hours

Time taken to cover the total trip = Reciprocal of
`(1)/(8)` x (
`1\frac14` )

`=\frac81*((5)/(4))\\\\=2*5\\\\=10\text{ hours}`

Therefore , it will take 10 hours to complete the trip.
