`a) \: \: slope \: of \: you = (250 - 150)/(5 - 3) \\ \\ = (100)/(2) \\ \\ = 50 \\ \\ \implies \: speed \: of \: you = 50 \: kmph \\ \\ slope \: of \: friend = (240 - 120)/(8- 4) \\ \\ = (120)/(4) \\ \\ = 30 \\ \\ \implies \: speed \: of \: friend = 30 \: kmph \\ \\ b) \: \: difference \: between \: the \: speed \: \\ of \: you \: and \: your \: friend \\ = 50 - 30 \\ = 20 \: kmph`
