jody has already hiked 4 kl the trail is 12 kl she can hike 2.5 per hour how many hours does she need to hike

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

No order to answer this question, you will need the formula that ded times a obtuse triangle. This formula will state that a obtuse triangle is > something or < something. The longest side is 20 which is opposite of the right angle,
