A boy cycles 15kilometer to school in 55 minutes,find his average speed in a meter per second
1 km = 1000 m
15 km = 15000 m
1 min = 60 s
55 min = 55 • 60 = 3300 s
15000 m/ 3300 s =
300 • 50 / 300 • 11 = 50 / 11 m / s
To find the average speed in meters per second, we need to convert kilometers to meters and minutes to seconds.
1 kilometer is equal to 1000 meters.
So, the boy cycled 15 kilometers, which is equivalent to 15,000 meters.
Now, let's convert the time from minutes to seconds.
1 minute is equal to 60 seconds.
Therefore, the boy took 55 minutes, which is equivalent to 55 x 60 = 3300 seconds.
To find the average speed, we divide the distance by the time:
Average speed = Distance / Time
Average speed = 15,000 meters / 3300 seconds
Calculating this gives us:
Average speed ≈ 4.55 meters per second.
Therefore, the boy's average speed is approximately 4.55 meters per second.
To find the average speed in meters per second, we need to convert the distance traveled from kilometers to meters and the time taken from minutes to seconds.
1 kilometer is equal to 1000 meters, so to convert 15 kilometers to meters, we multiply 15 by 1000:
Distance in meters = 15 kilometers * 1000 meters/kilometer = 15000 meters
Similarly, 1 minute is equal to 60 seconds, so to convert 55 minutes to seconds, we multiply 55 by 60:
Time in seconds = 55 minutes * 60 seconds/minute = 3300 seconds
Now, we have the distance in meters (15000 meters) and the time in seconds (3300 seconds). To calculate the average speed, we divide the distance by the time:
Average speed = Distance/Time = 15000 meters / 3300 seconds
Calculating this value, we find:
Average speed = 4.545 meters/second
Therefore, the boy's average speed is approximately 4.545 meters per second.
