How fast is the ball seem to be moving?
This question illustrates relative velocity;
Since the ball and the train moves in the same direction, the required velocity relative to the person standing behind is:
i.e. we add both velocities
Answer: try multiplication for the answer or use photomath
Step-by-step explanation:
The answer is B since a negative number being subtracted cancels out and becomes a number, for example: since its -(-3) it becomes positive.
3 gallons per second
Or
1/3 second per gallon
Just do 150 gal over 50 seconds
Or reverse it to 50 sec over 150 gallons
So you get 3 gallons occur each 1 second or the it takes 1/3 of a second for each 1 gallon to flow
