Question

22. A particle travels 24.6 km in 30 minutes.
Find the speed of the particles
in m/s​

Answer 1

Answer:

Speed = Distance by time.

30 mins = 1/2 hour

Speed = 24.6 / 1/2

Speed = 24.6 × 2

Speed = 49.2 km / h

1 km / h = 5/18 m/s

49.2 * 5/18 = 13.6 m/s

Answer 2

Answer:STEP BY STEP

frist we change km in m

   so, 24.6km  in m= 24.6 *1000

                                =24600m

then,

          minutes in second

              so, 30 minutes in second =30 *60

                                                          =1800sec

                                     

                                           AtoQ

              SPEED = DISTANCE /TIME

                               = 24600/1800

                                    = 13.6666 M / S
