Answer:

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.

  • Average Speed=1.2 miles per hour.
  • Distance =3.72 miles

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.

1/3(6z+7.2)=0.5(8z+2)-0.4 please hurry this is for now
Crazy boy [7]

Answer:

z = - 0.78

Step-by-step explanation:

Given:

1/3(6z+7.2)=0.5(8z+2)-0.4

Open parenthesis

2z + 2.4 = (4z + 1) - 0.4

2z + 2.4 = - 1.6z - 0.4

Collect like terms

2z + 1.6z = - 0.4 - 2.4

3.6z = -2.8

z = -2.8 / 3.6

= - 0.78
