If a runner who runs at a constant speed of p miles per hour runs a mile in exactly p minutes what is the integer closest to the value p

Describe a situation where it would be beneficial to round decimals to the nearest dollar. explain why you would use rounding in that situation.

How far from the average mileage is any one of these values, on average? or, in more technical terms, what is the average of the absolute value of the variations of the mileages? for the purposes of this problem, we will call this result the uncertainty in the mileages. answer in units of mph. your answer must be within ± 0.1 mph.
