A space shuttle orbiting Earth travels about 40 miles in 10 seconds. What is the average speed of the space shuttle in miles per second?

Speed = distance / time

Speed = 40 miles / 10 seconds

Speed = 4 miles per second.

y=mx+b

step-by-step explanation:

m slope

b y-intercept

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
