A runner travels 1.49 km in 5 min and 30 seconds. What is the velocity in m/s? Answer to two decimal places.
1.49km/330s * 1000m/km = ____ m/s
To find the velocity in m/s, we need to convert the distance and time to consistent units.
First, let's convert the time to seconds. We have 5 minutes and 30 seconds, which is equivalent to 330 seconds (5 minutes x 60 seconds + 30 seconds).
The distance traveled is given as 1.49 km. We need to convert this to meters since the velocity is measured in m/s. There are 1,000 meters in one kilometer, so we can multiply the distance by 1,000 to convert it to meters: 1.49 km x 1,000 = 1,490 meters.
Now that we have consistent units, we can calculate the velocity. Velocity is determined by dividing the distance traveled by the time taken.
Velocity = Distance / Time
Velocity = 1,490 meters / 330 seconds
Calculating this expression, we get:
Velocity = 4.51515 m/s
Rounded to two decimal places, the velocity is 4.52 m/s.
To find the velocity in m/s, we need to convert the distance and time to the appropriate units and then divide the distance by the time.
First, we need to convert the distance from km to meters. Since 1 km is equal to 1000 meters, we can multiply 1.49 km by 1000 to get the distance in meters:
1.49 km * 1000 m/km = 1490 m
Next, we need to convert the time from minutes and seconds to just seconds. To do this, we multiply 5 minutes by 60 seconds/minute and then add 30 seconds:
(5 min * 60 s/min) + 30 s = 300 s + 30 s = 330 s
Now that we have the distance in meters (1490 m) and the time in seconds (330 s), we can calculate the velocity by dividing the distance by the time:
Velocity = distance / time
Velocity = 1490 m / 330 s
Calculating this division gives us the velocity in m/s:
Velocity ≈ 4.52 m/s
Therefore, the velocity is approximately 4.52 m/s.
