We use the rate-time-distance formula to write the distance D traveled by John and Peter (same distance D) D = 3 x and D = 2 (x + 20) The first equation can be solved for x to give. Here, v is final velocity ( = 0 ms^-1), u is the initial velocity ( = 80 kmh^-1 = 22.22 ms^-1), a is the acceleration ( = -6.2 ms^-2) and s is the distance ( = ? (A) 50 (B) 48 (C) 47 (D) 46 (E) 45 This site is using cookies under cookie policy . Therefore we can substitute 2w for l in the equation for the perimeter giving: p = 2*(2w) + 2w For this problem we are also told the perimeter is 3*13.7 which is 41.1 so we can substitute 41.1 for p .
