Answer :
Final answer:
The gradient for each slope is as follows: a. 1/20, b. 17.5, c. 1/5, d. 7.5.
Explanation:
a. To find the gradient, divide the change in vertical distance by the change in horizontal distance. In this case, the road falls 10 m for every 200 horizontal meters. So the gradient would be 10/200 or 1/20.
b. The cliff rises 35 metres for every 2 metres horizontally. To find the gradient, divide the change in vertical distance by the change in horizontal distance. So the gradient would be 35/2 or 17.5.
c. The plane descends 2 km for every 10 horizontal kilometres. To find the gradient, divide the change in vertical distance by the change in horizontal distance. So the gradient would be 2/10 or 1/5.
d. The submarine ascends 150 m for every 20 horizontal metres. To find the gradient, divide the change in vertical distance by the change in horizontal distance. So the gradient would be 150/20 or 7.5.
