Okay — typically when you talk about how fast something on land is going, you talk in terms of miles per hour, right?

So how many hours is 120 minutes?

And if the airplane goes 800 miles in that many hours, what is it’s average speed? How many miles per hour is it going? It’s a ratio — miles/hour

The second one works the same way.

I agree with above…

120 minutes divided by 60 = 2 hours

800 miles divided by 2 hours = 400 miles per hour

1/2 hour = .5 hours

2 miles dived by .5 = 4 miles per hour

ur supposed to find distance/time (miles per hour, meters per second, etc.) so…

800 miles/120 min= 6.66 mi/min

2 miles/.5 hour= 4 mi/hr

i’m right too…you can decide whether you want miles/hr or miles/min, either one still answers the question
