Aspeed limit of 100 kilometers per hour (kph) is approximately equal to 62 miles per hour (mph). write an equation relating kilometers per hour, k, to miles per hour, m. then predict the following measures. round to the nearest tenth. a) a speed limit in mph for a speed limut of 75 kph b) a speed limit in kph for a speed limit of 20 mph

1- is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis. 2- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis. 3- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in part b?
