A runner travels 1.65 km in 5 min and 30 seconds. What is the velocity in m/s? Answer to two decimal places.
I think I have answer
since v=d/t
convert 5 min 30 sec to seconds 330 seconds and 1.65km to 1650m
1650m/330sec answer: 5m/s
Am I right?
5*60 +30 = 330 s
1650 meters
5
yes
five and a half minute mile, not a track star but not dead either.
Yes, you are correct. The velocity can be calculated using the formula v = d/t, where v is the velocity, d is the distance, and t is the time. You correctly converted 5 minutes and 30 seconds to 330 seconds, and 1.65 km to 1650 m. Dividing 1650 m by 330 seconds gives a velocity of 5 m/s. Well done!
Yes, you are on the right track!
To find the velocity, you need to divide the distance traveled by the time taken. Let's convert the time to seconds first.
Given:
Distance = 1.65 km
Time = 5 minutes and 30 seconds
To convert minutes to seconds, multiply the number of minutes by 60 (since there are 60 seconds in a minute):
5 minutes = 5 * 60 = 300 seconds
Therefore, the total time taken is 300 seconds + 30 seconds = 330 seconds.
Now, convert the distance from kilometers to meters:
1 kilometer = 1000 meters
So, 1.65 kilometers = 1.65 * 1000 = 1650 meters.
Now you can plug the values into the velocity formula:
Velocity = Distance / Time
Velocity = 1650 meters / 330 seconds = 5 meters per second.
You are correct! So, the velocity is 5 m/s.
