Two friends workout on the treadmill one friend walked 2 miles in 3/4 of an hour the second friend walked 1 3/4 mile in 30 minutes who walked faster
rate

Second friend walks faster

Solution:

Two friends workout on the treadmill

To find who walked datser, let us first find the unit rate

Unit rate = miles walked in 1 hour ( miles per hour )

One friend walked 2 miles in of an hour

Therefore,

Thus unit rate of first friend is 2.67 miles per hour

The second friend walked mile in 30 minutes

First convert the mixed fraction to improper fraction

Convert 30 minutes to hours

Therefore,

Thus unit rate of second friend is 3.5 miles per hour

On comparing, unit rate of both friends,

unit rate of second friend > unit rate of first friend

3.5 > 2.67

Thus second friend walks faster

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
