Question

It takes Johnny 42 minutes to get to the zoo after 18 minutes he stopped to get gas for his car what writing equation to express how many more minutes he had to travel after getting gas

Answer 1

18 + x = 42
18 (miles traveled until gas was needed) + x (the miles traveled without needing gas) = 42 (total miles traveled)

Answer 2

18 + t = 42, t = 24

Explanation:

We know that Johnny travelled 18 minutes without needing the gas.

Let t represent the number of minutes he had to travel after getting gas.

Then, the total time to get to the zoo will be:

18 + t

Since it takes 42 minutes in total, the final equation will be:

18 + t = 42

t = 24
