Question

distance is 200km and time is 5hr20 min then what is speed in m/sec? ​

Answer 1

Answer:

Step-by-step explanation:

Convert km to m

200km = 200000m

Time taken in seconds;

5`hr = 300minutes

(300 + 20) minutes            

1 minutes = 60 seconds

Therefore, 5hr 20 min= 320 min × 60 sec

                                     = 19200 sec

Speed = (Distance ) /(Time )

= 200000/19200

= 10. 42m/s
