### How to Convert Km/hr to m/sec?

To convert Km/hr to m/sec follow the below listed guidelines. They are as such

We know 1 km = 1000m and 1 hour = 60 minutes and in turn 1 minute = 60 sec

1 hour = 60*60 = 3600 sec

Dividing km/hr we have = 1000m/3600sec

On simplifying we have km/hr = 5/18 m/sec

Therefore to convert from km/hr we simply multiply with 5/18.

**Solved Problems on Converting Km/hr to m/sec**

1. Convert 54 km/hr to m/sec?

Solution:

To convert, 54 km/hr to m/sec simply multiply with 5/18

= 54*5/18

= 15 m/sec

Therefore 54km/hr converted to m/sec is 15m/sec.

2. The speed of the bike is 108 km/hr, what is its speed in m/sec?

Solution:

Given Speed of Bike = 108 km/hr

To obtain the Speed in m/sec simply multiply with 5/18

= 108*5/18

= 30 m/sec

Therefore, the Speed of the Bike is 30 m/sec.

3. A car covers a distance of 120 km in the first three hours, 50 km in the next 1 hour, and 25 km in the next 1/2 hour. Convert the speed into m/sec?

Solution:

Total Distance traveled by the Car = (120+50+25) = 195 km

Total Time Taken = (3+1+1/2) = 4 1/2 hrs

Speed of the Car = 195km/4.5 hr = 43.3 km/hr

Speed of the Car in m/sec = 43.3*18/5

= 155.88 m/sec

### How to Convert m/sec to km/hr?

Follow the below listed guidelines inorder to change between m/sec to km/hr

We know 1km = 1000m

thus, 1m = 1/1000 km

1 hour = 3600 sec

thus, 1 sec = 1/3600 hr

applying the same we have 1 m/1 sec = (1/1000km)/(1/3600 hr)

= 3600km/1000hr

= 18/5 km/hr

Therefore, to convert from m/sec to km/hr simply multiply with 18/5

**Solved Problems on Converting m/sec to km/hr**

1. Convert 60 m/sec to km/hr?

Solution:

Given 60 m/sec

to change to km/hr multiply with 18/5

= 60*18/5

= 216 km/hr

2. The speed of a cyclist is 15 m/sec. find the speed in km/hr?

Solution:

Speed of a Cyclist = 15 m/sec

To convert to km/hr multiply with 18/5

= 15*18/5

= 54 km/hr
