Answer

a) 186 mph b) 763 mph

Work Step by Step

We are asked to round to the nearest whole number, so we eliminate all decimals. If the tenth decimal place is 5 or greater, we add 1 to the whole number. If not, we just write the whole number without the decimal portion. Doing this, we find: a) 186 mph b) 763 mph
