Sherri hikes on the Pacific Coast trail. She plans to hike 3.72 miles. If she hikes at an average speed of 1.2 miles per hour, how long will she hike?

3.1 hours

Step-by-step explanation:

Average Speed=Distance Traveled ÷ Time Taken

Sherri plans to hike 3.72 miles  at an average speed of 1.2 miles per hour.

Therefore:

1.2 miles per hour=3.72 miles ÷ Time

1.2 miles per hour X Time=3.72 miles

Time = 3.72 ÷ 1.2 hours

Time taken by Sherri=3.1 hours

Sherri will hike for 3.1 hours.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

answer: 5 17/33 % (to the tenth)

step-by-step explanation:

he guessed: 34.5 pounds

actual weight is 32.7

there for he is off:

34.5 -32.7 = 1.8

32.7 is the 100%

1.8 represents %? of 32.7

therefore:

32.7   - 100%

1.8     -     x%

x= 1.8*100%/32.7% = 18*100%/327%

x=1800%/327%   = (5 165/327)%

to the tenth:

5 17/33 %
