He went around 24 times and 4 times is a mile so 24/4 will tell us how many miles he biked. He biked 6 miles in thirty minutes. The formula distance = rate(time) will tell you how fast he is going.

6 = r(1/2)    divide each side by 1/2 (The time has to be in hours)
12 = r 
So he was going 12 miles an hour.

A rectangle has an area of 40 sq units , then length is 6 units greater than the width
devlian [24]

Answer:

A=L*W

Let w be width

L=(w+6)

40=(w+6)*w

40= w^{2} +6w

w^{2} +6w-40=0

w^{2}+10w-4w-40=0  

w(w+10)-4(w+10)=0

(w-4)(w+10)=0

w=4

Length= 10 units

Width=4 units
