45 min = 3/4 hrs
4 km / (3/4 hrs) = 4*4 km/3 hrs = 5.33333... km/hrs
You divide the distance traveled by the time.
All you must do is multiply 0.10 km by the number of minutes in the given time, in this case 120. She will go 12 km.
velocity=500 miles per hour
A/B
Nine minutes.
5 1/3 kmh
14.634 kilometers per hour.
To convert 1 kilometer to meters, multiply by 1000. So, 1 kilometer is 1000 meters. To convert 4.1 minutes to seconds, multiply by 60. So, 4.1 minutes is 246 seconds. The velocity of the bicycle would be 1000 meters / 246 seconds = 4.07 meters per second west.
The person could walk 2.7 kilometers in 30 minutes at a velocity of 1.5 m/s. This is calculated by multiplying the velocity (1.5 m/s) by the time (30 minutes, which is 1800 seconds). 1.5 m/s x 1800 s = 2700 meters = 2.7 kilometers.
-- The speed is 888/9 meters per minute, 51/3 kilometers per hour,or 128 kilometers per day.-- We don't know the velocity, because we have no information aboutthe direction of the speed.
Hint: 10000 meters = 10 km, 30 minutes = ½ hour... 10,000 meters in 30 minutes = 10 kilometers per 0.5 hour = 20 kilometers per hour
The bike's average speed during that time was 51/3 kilometers per hour.There's no way to determine its velocity, because the question doesn't giveany information about the bike's direction ... a necessary part of velocity.
You divide the distance traveled by the time.
With the information given, it's not possible to calculate what it is now. But during that 90 minutes, its average velocity was 50 kph north.
Time = Distance/Velocity = 2000/55 = 36.3636.. hours = 36 hours 21.8181.. minutes
The typical velocity of S-waves in the Earth's crust ranges from about 3 to 8 km/s. Within the first 4 minutes of travel, the S-waves could have propagated tens or hundreds of kilometers, depending on the exact velocity and path.
All you must do is multiply 0.10 km by the number of minutes in the given time, in this case 120. She will go 12 km.
