Answer» distance travelled by snail=1mtime taken by snail =10swe know, speed=distance travelled/time taken:.speed of snail=DT/TTfor this first we have to convert the distance into km and time into hourSo, 1m=1/1000m =0.001kmnow, 10s=10/60 =0.16hnow, the speed of snail=0.001/0.16 =0.006km/hans) speed of snail in km/h is. 006km/h |
