Question

A straight access ramp rises $75$ cm over a horizontal distance of $700$ cm. On a scale drawing, the lower end is represented by $A(0,0)$ and the upper end by $B(700,75)$. Find the gradient of $AB$. The design limit is a gradient not exceeding $0.125$. State, with a reason, whether the ramp satisfies the limit.

Accepted Answer

(a) $0.1071$; (b) yes.
