A straight pipe which carries water from a reservoir at r to a tap at t. R and t are 2km apart horizontally and r is 500CM ABOVE THE LEVEL OF T. FIND THE LENGTH OF THE PIPE . SHOW WORKING
draw a diagram. You have a right triangle and you want to find the hypotenuse RT. If all distances are expressed in meters, then this will be
√(2000^2 + 0.5^2) = 2000.000625
which is so close to just 2000m as to be indistinguishable.
