Question

sita was running on a circular track of length 500 meters.she completed her first round in 3 min .in her second round she took a detour which increases the distance she ran by 10%.but sita ran faster and took 10% less than the first round .what was her speed in the second round ?

Answer 1

Answer:

3.395 m/s

Step-by-step explanation:

Second Round :

Distance covered = 500 + 10% of 500

                              = 500 + 50

                              = 550 m

Time = 3 - 10% of 3

        = 3 - 3/10

        = (30 - 3)/10

        = 27/10

        = 2.7 mins

        = 162 secs

Speed = Distance/Time

           = 550/162 m/s

          = 3.395 m/s
