Question

3) Johann has traveled 15 miles from his station on the train. He will continue onthe train at 80 miles per hour. If he ends up traveling a total of 615 miles, howmuch longer did it take him?

Answer 1

Step 1 :

In the question, we are told that:

Johann has traveled 15 miles from his station on the train.

He will continue on the train at 80 miles per hour.

If he ends up traveling a total of 615 miles,

we are meant to find how much longer did it take him.

Step 2:

Let t represents the time, so that we have the following:

`15\text{ + 80t = 615}`

Solving this, we have that:

`\begin{gathered} 80t\text{ = 615 - 15} \\ 80\text{ t = 600} \\ \text{Divide both sides by 80, we have that:} \\ t\text{ = }(600)/(80) \\ \text{ t}=\text{ 7. 5 hours} \end{gathered}`

CONCLUSION:

The final answer is 7. 5 hours
