Jan can run at 7.5m/s and Mary at 8m/s. On a race track Jan is given a 25m head start, and the race ends in a tie. How long is the track?
I have attempted to come up with an equation, but have failed. Horribly. I tried 8x = 7.5(x-25) but it doesn't work out. Can someone explain to me what the equation would be and why?
