Andrew walked 3/4 mile in 10 minutes. jill walked 4/5 mile in 15 minutes. what was the difference in their speeds, in miles per hour?

1.3 miles per hour

Step-by-step explanation:

3/4 / 10 = 3/40

4/5 / 15 = 4/75

3/40 x 60=4.5

4/75 x 60 = 3.2

4.5 - 3.2 = 1.3

1.3 mph

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.

mean, 40.6
