Answer 1

Solution:

His speed is 121200 meters per hour.

Step-by-step explanation:

Arijit travels 20 Km and 200 meters in 10 minutes.

We are asked to find his speed in m/hour.

Now, 20 km and 200 m are equivalent to 20200 meters.

And 10 minutes is equivalent to 10/60 = 0.167 hours.

Therefore, if Arijit travels at a constant speed, then his speed in meters per hour is 20200/0.167= 121200 meters per hour.
