A dragonfly traveled at a rate of 35 miles per hour for 2.5 hours. What distance did the dragonfly travel?

Well, first do 35x2.5, which equals 87.5. This is your answer, but how do you get to it?

35 miles an hour, and it says he goes for 2.5 hours. This is the same as saying he will go for 150 minutes, and he'll travel for 35 mph. Simplified.

Answer:87.5
