So u need to find the circumference of the half circle by finding the circumference of the whole circle and dividing by 2 so that gives you 12.565 then u find the perimeter of the rectangle but not the 4th side cause that’s on the inside when u do that u get 10+10+8 which is 28 then add the half circle and I get 40.565 ft but round to nearest hundred so 40.56 ft
The total length of Jiamin's trip was
distance = speed × time
distance = (52 mi/h) × (5 h) = 260 mi
The distance Jiamin traveled in her first 2 hours was
distance = (50 mi/h) × (2 h) = 100 mi
That means she traveled the last (260 -100) mi = 160 mi in the remaining 3 hours. Her average speed for that portion of the trip was
speed = distance / time
speed = (160 mi) / (3 h) = (160/3) mi/h ≈ 53 1/3 mi/h
Jiamin's average speed for the last 3 hours of her trip was 53 1/3 mi/h.
