A snail cover a distance of 100 metres in 50 hours. calculate the average spees of snail in km/h.
average speed = total distance travelled / time taken
so,
v = d / t
here
d = 100m = (100/1000) km = 0.1 km
t = 50 hours
thus
v = 0.1/50 = 0.002 km/hr
A train covers 50 km with the speed of 100 km per hour and another 50 km with a speed of 50 km per hour. Find the average velocity.
