traveledAnswer:

225 km

Step-by-step explanation:

We know that in 1 hour he will travel 90 km, so in 2 hours, he will travel double what he did in one, so multiply 90 by 2 and we get 180. If he travelled 90 km in 1 hour, then for half that time he traveled half the distance, so 90/2 is 45. Now add 180 and 45 and we get 225 km. Hope this helps!
