An airplane travels 42 miles in 1/4 hours how many miles does it travel per hour?

1. what you know: the plane travels 42 miles in a quarter of an hour.
2. what you need to find out: the miles traveled in an hour.

ok, so how many quarters are in a whole? (look at the denominator of the fraction. the denominator is the bottom number of the fraction, which is four.)

since 42 is the value in 1/4 of an hour, 42×4 is the value is 4/4 or a whole hour. so find the product (the answer you get when you multiply two numbers) of 42 and 4.

168 mph since 42 miles in 1/4 and multiply 42 x 4 because 4/4 is a hour and the answer would be 168

Here are the answers to the ones that i could see.
