Answer 2

Answer:

1)  1.11 meter/sec

Step-by-step explanation:

1) Ambika walks at a speed of 4 km/hour.

So in 1 hour she covers the distance of 4 km.

We know that, 1 hour = 3600 seconds.

Also, 1 km=1000 meter.

  so, 4 km= 1000*4 meter.

          = 4000 meter.

Since speed= Distance/ Time.

          = 4000/3600

          = 10/9  

          = 1.11 meter/sec

Hence speed of Ambika in meter/sec is 1.11 meter/sec.

2) Insufficient data in the postman sum since distance or any other data is not provided.

Insufficient data in the Rahul sum since time taken to complete the round is not provided.
