Answer:
3,2 hours
Step-by-step explanation:
Let number of hours = h
Given that she can hike 2.5 per hour. So that means distance travelled in "h" hours will be 2.5h
It is also given that Jody has already hiked 4 kilometers.
So total distance travelled by Jody in "h" hours will be (2.5h+4)
Given that trail is 12 kilometers long.
That means Jody has to travel for 12 kilometers. In that case both values will be equal and we get equation:
2.5h+4=12
We were asked only to find the equation not the value of h, so answer will be 2.5h+4=12
