357 miles in 5 hours how many miles per hour

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.

the easiest way to do these would be to solve the equations. if you can solve the equation than you can solve these problems.
