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?
To convert, 54 km/hr to m/sec simply multiply with 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?
Given Speed of Bike = 108 km/hr
To obtain the Speed in m/sec simply multiply with 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?
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)
= 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?
Given 60 m/sec
to change to km/hr multiply with 18/5
= 216 km/hr
2. The speed of a cyclist is 15 m/sec. find the speed in km/hr?
Speed of a Cyclist = 15 m/sec
To convert to km/hr multiply with 18/5
= 54 km/hr
