Gary can hike on level ground 3 miles per hour faster than he can on uphill terrain. Yesterday, Gary hiked 10.25 miles, spending 3 hours on level ground and 2 hours on uphill terrain. What is Gary's average hiking speed on level ground

13.14

Step-by-step explanation:

2s + 5(s-3) = 31

2s + 5s - 15 = 31

7s = 31 + 15

7s = 46

s = 46/7

s ~ 6.57 mph on level ground

Check this by finding the distances

2(6.57) = 13.14 mi

i assume that by 5 you mean 5 gallons.

(20)(0.25) = 15

removing 15 gallons reduces the tank from 20 to 5.

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=
