Anjali swam for 50seconds at a speed of 4.5m/s. Then, she swam for another70secondsat a speed of 1.5m/s. Find the distance covered by anjali in metres.
As we know,
Distance=speed×time
Distance covered by Anjali in first 50seconds=4.5×50=225metres
distance covered by Anjali in next 70seconds=1.5×70=105metres
So , The total distance covered by Anjali = 225+105=330metres
A runner covers a distance of 270metres in 30seconds.
Find his speed in m/s
Mowgli, while trying to escape from Shere Khan, ran 500 metres in 10 seconds to reach near the river and swam 200 metres in 20 seconds before climbing the trees. Then he climbed 100 metres in 10 seconds before finding peace on top of a tree.
Statement: Mowgli’s average speed in this journey is (50010+20020)+10010)×13=703 metres per second , which is the averages of speeds.
