A boy runs 800metres in 3 minutes,what is his speed in kilometers per hour
To find the speed in kilometers per hour, we need to convert the distance from meters to kilometers and the time from minutes to hours.
800 meters is equal to 0.8 kilometers (since 1 kilometer = 1000 meters).
3 minutes is equal to 3/60 = 0.05 hours (since 1 hour = 60 minutes).
To find the speed, we divide the distance by the time:
Speed = Distance/Time
Speed = 0.8 kilometers / 0.05 hours
Speed = 16 kilometers per hour
Therefore, his speed is 16 kilometers per hour.
To find the speed in kilometers per hour, we need to convert the distance from meters to kilometers and the time from minutes to hours.
1. Convert the distance from meters to kilometers:
- There are 1000 meters in 1 kilometer. So, divide 800 by 1000 to get the distance in kilometers: 800m / 1000 = 0.8km.
2. Convert the time from minutes to hours:
- There are 60 minutes in 1 hour. So, divide 3 minutes by 60 to get the time in hours: 3min / 60 = 0.05h.
3. Calculate the speed:
- Divide the distance by the time: 0.8km / 0.05h = 16km/h.
Therefore, the boy's speed is 16 kilometers per hour.
To calculate the speed of the boy in kilometers per hour, we first need to convert the distance from meters to kilometers and the time from minutes to hours.
1 kilometer = 1000 meters
1 hour = 60 minutes
So, the distance covered by the boy in kilometers would be 800 meters / 1000 = 0.8 kilometers.
The time taken by the boy in hours would be 3 minutes / 60 = 0.05 hours.
Now, to calculate the speed, we divide the distance by the time:
Speed = Distance / Time
= 0.8 kilometers / 0.05 hours
= 16 kilometers per hour
Therefore, the speed of the boy is 16 kilometers per hour.
