Can anyone help in a dabate with my Maths Teacher. She says gradients are rise over run or something she calls tangents. But my dad always told me when measuring the gradient of a road you wouldn't go digging a horizontal tunnel and measure that - you'd naturally measure how far along the road you'd travelled.
Also if we had a road at 45 degrees according to my teacher that would have a gradient of 100%. But that's not logical. A vertical cliff should be 100%. 45 degrees should be 50%.
I remember going on holiday in Wales years ago and my dad towing a caravan and family of 4 up a 1 in 3 and a half. However you measure it that was steep!
