Velocity - math word problems - page 15 of 50
The velocity of an object is the time rate of change of its position. Velocity is a specification of an object's speed and direction of motion (e.g. 20 m/s to the south).In everyday use and in kinematics, the speed of an object is the magnitude of its velocity (the rate of change of its position) - scalar.

- Long hot dog
In Kostelec above Black Forest, they made a record-long hot dog. When he slowly moved it to the square, one of the spectators decided to measure its length: the size of his footprint was 28 cm; he measured 20 feet in the travel direction and counted 5 fee - Straight-line 42511
The lady and the gentleman run toward each other in an even, straight-line motion. The lady runs at a speed of 25.2 km/h, and the man at a speed of 18 km/h. When they are 300m apart, we start timing. How long before the lady and the man fall into each oth - Radiators
