Question

An earthworm of length 15 cm is crawling along at 2 cm/s. An ant overtakes the worm in 5 seconds. How fast is the ant walking?​

Answer 1

Answer:

The ant must be walking at a speed of 6cm/sec

Answer 2

Answer:

3.5cm/s

Step-by-step explanation:

length of worm = 15cm

speed of worm = 2cm/s

distance covered by the worm = 5/2 = 2.5cm

So, the length the ant had to travel to overtake the worm = 15+2.5 = 17.5cm

Speed of worm = distance \ time = 17.5/5

                                                         = 3.25cm/s
