3/4 mile track. 3/4 mile X 2 laps = 1 and 1/2 miles 3/4 mile X 3 laps = 2 and 1/4 miles For 2 exact miles you need to walk 2 and 2/3 laps of the track. However, may I suggest just walking the 2 and 1/4 miles (3 laps) to keep life simple?
Runners 1 and 3 are at the start, runners 2 and 4 are half-way (100 metres) along the track. They finish at the start.
(3-1/2) x (1/4) = (7/2) x (1/4) = 7/8 mile
1/4 x 4/1 1 x 4= 4 4 X 1= 4 1/4 X 4/1= 4/4 = 1 The answer is 1.

Use the chain rule:d/dx √(4 - x) = d/dx (4 - x)1/2= 1/2 (4 - x)-1/2 x d/dx (4 - x)= 1/2 (4 - x)-1/2 x -1= -1/2 (4 - x)-1/2 or -1/2√(4 - x)
