Blessed day to you....You are travelling 40mph{64kph} on a dry road in a well maintained vehicle.You are alert and need to brake in an emergency.You are able to stop in less than.....
(a)73 meters(240 feet)
(b)85 meters(230 feet)
(c)36 meters(120 feet)
(d)76 meters(250 feet)
A simple way to work out this question is:you take the speed 40mph and divide the first number which is 4 by 2...you then multiply your answer to the 40....the answer you get you then add it to the 40 to get the overall stopping distance.....
40(4\2=2)
40 x 2=80(braking distance)
40 +80=120
answer 120feet stopping distance
blessed love to all......
