An 8th grade class traveled 110 km and the bus was going 55 km/hr. How long did it take?

2.0 hr
0.5 hr
55 hr
6050 hr

2 hours

Step-by-step explanation:

So this is a pretty simple question :)

First you want to take note that the bus is traveling 55km in 1 hour. Now you can think of this in 2 ways. the easiest way to find the answer is to do

110km ÷ 55km = 2

But you can also think of it through multiplication. This means you can of it as:

55km for 1 hour so how many for 2?

55km × 2 = 110km

This shows that 2 hours is correct!

Hope that helps :)
