Zachary travels on a journey of 50 miles. he spends half of his time riding a horse and half of it walking. the horse covers 9 miles every hour. when he walks, he covers 3.5 miles an hour. how much time does it take him to complete the journey?

the area of the rectangle is 35units^2.

step-by-step explanation:

graph it and find the distance.

it is a 5*7 rectangle.

therefore the area is 35units^2.

t= half of the arc subtended by t.

r= half of the arc subtended by r.  

t+r= half of the arc subtended by t + half of the arc subtended by r= half of 360=180

step-by-step explanation:

i believe that the answer is y+6=1/3(x+2)
