Jen rode her bike 1/5 of a mile to her friend's house. It took her 5 minutes to get there. What was Jen's speed?

2.4 miles per hours

Step-by-step explanation:

if she traveled 1/5 of a mile in order for you ro do this you must first teun it into a full mile so times it by the required amount to equal one which would be five.

1/5 of a mile x 5 = 1

you must do this also to the time

5 minutes x 5 = 25 minutes

it takes her 25 minutes to travel one mile so because miles per hour is a ration you must find the amount in hours and not minutes.

So you must divide the hour equivilent by 25 minutes.

so if 1 hour equals 60 minutes

60 divided by 25 = 2.4

that is how you find miles per hour

if x decreases by 4 then y increases by 10

step-by-step explanation:

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13
