Question

The speed of 45 m/sec when converted in to km /h is​

Answer 1

Answer:

162 km/hr

Step-by-step explanation:

1 km = 1000m

1000m = 1 km

1m = 1

       ---

     1000

45m = 45/1000

1hr = 60 * 60 seconds = 3600 seconds.

3600 sec = 1 hr

1 s = 1/3600 hr

thus speed = distance/time:

45*3600/1000*1 = 162 km/hr
