60km per hour west.
50 km/hr
The velocity of the train can be calculated by dividing the distance traveled by the time taken. In this case, the train travels 140 kilometers west in 2 hours. Therefore, the velocity is 140 km / 2 hours = 70 km/h west.
14.634 kilometers per hour.
It's 70 kilometers per hour west.
The change of velocity is 75 km/hr west.
The equation for velocity is velocity=distance/time. So you would solve the problem as follows. 240km/4h=60km/h
50 km/hr
The velocity of the car is 32 mph
The velocity of the train can be calculated by dividing the distance traveled by the time taken. In this case, the train travels 140 kilometers west in 2 hours. Therefore, the velocity is 140 km / 2 hours = 70 km/h west.
14.634 kilometers per hour.
It's 70 kilometers per hour west.
The change of velocity is 75 km/hr west.
60 km/h
It's in the north-east, about 240km North of Tokyo.
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.
Speed - but NOT velocity.
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.
