Question

An ant travels at a constant rate of 30 cm every 2 minutes.

At what pace does the ant travel per centimeter?
At what speed does the ant travel per minute?

Answer 1

Answer:

0.25 cm/s and 0.0025 m/s

Step-by-step explanation:

Distance covered by the ant = 30cm

Time taken by the ant = 2 mins = 2x60s = 120s

Therefore, speed of the ant =

Speed = Distance/Time = 30/120 cm/s = 1/4 cm/s = 0.25 cm/s

Speed in minutes -

Speed in cnetimeters = 0.25 cm/s = 1/4 cm/s = 1 cm/4 seconds

Now, 1m=100cm. Therefore, 1cm = 1/100 meters (unitary method)

Therefore, speed in meters =

1/100 meters/4 seconds = 0.01 meters/4 seconds = 0.01/4 m/s = 0.0025 m/s

That's your answer.
