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.

Step-by-step explanation:

Given: Distance traveled by Ruby in $1\dfrac14$ hours = $\dfrac{1}{8}$ of Total trip.

i.e. Time taken to  complete $\dfrac{1}{8}$ of Total trip=  $1\dfrac14$ hours

Time taken to cover the total trip = Reciprocal of  $\dfrac{1}{8}$  x ($1\dfrac14$ )

$=\dfrac81\times(\dfrac{5}{4})\\\\=2\times5\\\\=10\text{ hours}$

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