a jogging path is 400 meters long. a jogger travels the entire length in 90 seconds.what is the speedof the jogger?
recall that speed is distance traveled over a certain time, or
v = d/t
substituting,
v = 400/90
v = 4.44 m/s
hope this helps~ :)
Well, if the jogging path is 400 meters long and the jogger travels the entire length in 90 seconds, we can calculate the speed by simply dividing the distance by the time. So, 400 meters divided by 90 seconds equals 4.44 meters per second. But if the jogger is anything like me, they might need a pit stop to catch their breath halfway through!
To calculate the speed of the jogger, you need to divide the distance traveled by the time taken.
Step 1: Convert the time to minutes.
90 seconds = 90/60 = 1.5 minutes
Step 2: Calculate the speed.
Speed = Distance / Time
Speed = 400 meters / 1.5 minutes
Step 3: Simplify the units.
Since the time is in minutes and the distance is in meters, we need to convert one of them for the units to match.
1 minute = 60 seconds
Speed = 400 meters / 1.5 minutes * (60 seconds/1 minute)
Step 4: Calculate the speed.
Speed = 400 meters / 1.5 minutes * 60/1
Speed = 400 meters / 1.5 minutes * 60
Step 5: Simplify the calculation.
Speed = 400 meters / 1.5 minutes * 60 = 1600 meters per hour
Therefore, the speed of the jogger is 1600 meters per hour.
To find the speed of the jogger, we need to divide the distance by the time taken.
First, let's convert the time taken to minutes. Since there are 60 seconds in a minute, we divide the time taken (90 seconds) by 60:
90 seconds / 60 = 1.5 minutes
Now we can find the speed by dividing the distance by the time:
Speed = Distance / Time
Speed = 400 meters / 1.5 minutes
To convert the speed to meters per second, we divide the distance by the time:
Speed = 266.67 meters per minute
To convert meters per minute to meters per second, we divide by 60:
Speed = 4.44 meters per second
Therefore, the speed of the jogger is approximately 4.44 meters per second.
