Surely you cannot be serious. He did 4 kms in half an hour, he therefore would have done 8 in an hour. He was therefore travelling 8 kilometers per hour................

you've were given km in protecting with 40 minutes. you opt for in protecting with hour. Convert 40 minutes to hours. it truly is .666666666 etc., or only 2/3 of an hour. To get km/hr, divide 2 via 2/3 hr. shop-change-turn: 2 * 3/2 = 6/2 = 3 km/hr (in case you had a calculator, you could do exactly 2 / (40/60) ] yet i don't have a calculator, so I only did via hand, with the objective to talk. and obviously now that you're already in km/hr, it truly is going to be an analogous answer, with instruments of km ( 3 km, in different words.)

speed = dist / time. therefore his speed is 4 / 0.5 = 8kmh or 4000 / (30x60) =2.22m per sec
