The velocity of the car is 32 mph
It's 70 kilometers per hour west.
It's 70 mph west
600 miles per hour due West
The closing velocity is speed1 plus speed2, so the trains are moving toward each other at 250 mph. 2000/250 = 8. The trains will meet in 8 hours.
Since acceleration is a change in velocity, if your velocity is constant (does not change), your acceleration is zero.
Average Speed = Distance Traveled / Time TakenVelocity = Speed and direction.Speed = 140 mi/ 2hrs = (140/2) mi/hr = 70 mi/hr.Direction = WestVelocity = 70 mi/hr west
60km per hour west.
The equation for velocity is velocity=distance/time. So you would solve the problem as follows. 240km/4h=60km/h
25/0.75 = 331/3 km per hourThat's the truck's average speed.If it spends the entire 45 minutes heading west, thenits average velocity is 331/3 km/hr west.
Distance = Rate X Time so.... Rate = Distance/Time 210 miles/30 hours = 7 miles per hour
speed = distance/time = 100mi/2h = 50mi/h
50 km/hr
