Astudent walks and jogs to college each day. the student averages 5 mph walking and9mph jogging. the distance is 8. she makes the trip in one hour. how far does the student jog?

Let x = the distance jogged

Then (8-x) = distance walked

:

Write a time equation: Time = dist/speed

:

Jog time + walk time = 1 hr

x%2F9 + %28%288-x%29%29%2F5%29 = 1

:

Multiply thru by 45 to get rid of the denominators, resulting in:

5x + 9(8-x) = 45

:

5x + 72 - 9x = 45

-4x = 45 - 72

-4x = -27

x = -27/-4

x = + 6.75 km jogged

:

:

Check: 8 - 6.75 = 1.25 km walked

6.75/9 + 1.25/5 =

.75 + .25 = 1

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.
