urs. Construct a plain scale to measure time in to a single minute.
F. = 1/200000. Show it on a distance covered in 21 minute.

​

Answer 1

Answer:

1.05 Km

Explanation:

When a train covers a distance of 120 Km or 120,000 m

In 4 hours or 4 x 60 = 240 minutes,

The speed will be distance / time = 120,000 /240 = 500m/min.

If the same speed is maintained, then the distance covered in 1 minute is speed x time = 500 x 1 = 500 metres.

Therefore, in 21 minutes, the distance covered will be 500 x 21 = 10,500 metres or 1.05 Km.
