A road has a gradient of 1/15 for 90 m.
Then there is a horizontal section 130 m long.
The final section has a gradient of 1/25 for 200 m.
a. Find the total height gained from start to finish.
b. What is the average gradient from start to finish?
I did the first part of the question and got 14 m which is right but then I don't understand the second part (b.) Could someone explain it to me, please?
