Well, if it traveled 28 miles in 30 minutes, then it would travel 56 miles in 60 minutes, which is the same as 56 mph.

simply multiply 28 miles by 2 because in 60 minutes (1 hour), the car will travel twice that distance (miles/hour), assuming the car travels at constant speed.

Proportion time. If you go 28 miles in 30 min, how many miles do you go in 60 min. Call "how many hours" = x. Then
(28/30) = (x/60)
I trust you can work this out.

Well, it travelled 28 miles in half an hour. How far would it have gone in an hour?

What shapes do you get once you chop up the sq. with a diagonal? 2 trangles. when you consider that all of us understand the sphere is a sq., which skill each and all of the aspects are equivalent (for this reason, in case you recognize one area, you recognize each and all of the aspects). So now you have a trangle with 2 aspects equivalent to 60 feet. you could now use Pythagorean's theorem: A (squared) + B(squared) = C (squared) A and B are your 2 aspects after which you merely remedy for C. solid luck!
