You need to solve this in parts.

First question to solve. If Victor is 12 km from his house, and he is going 18 km/hour, how long did it take him?

Once you know that, that is the time Alex left to go after Victor. But Alex is traveling much faster than Victor. For example, in 20 minutes Victor goes 4 km; in 20 minutes Alex goes 6 km.

I tutor math online if you would like to schedule sessions:)
