Question

Spring Village is 80m above sea level while the minor trigonometrical station at Bushy park is 40m. Given that the distance between the two places is 1km 500m. Calculate the gradient. Remember to write your answer as a ratio. *

Answer 1

Hello, Amy,

The gradient will be the change in elevation per change in distance. The elevation gain between the two locations is (80 - 40) = 40 meters. This change occured over a distance of 1.5 Km. One could go with:

80 m/1.5 km

But it seems likely that a gradient should have the same units. Let's convert km into meters: 1 km = 1000m

Now we have:

(80 m)/(1500 m). This reduces to 8/150
