Step-by-step explanation:
You will get the distance each ran by multiplying the speed each ran at and the time taken, and add the two results.
the distance puppy ran in 15 seconds= 6×15=90 meters
the speed of the kitten=2/3×6=4 meters per second
the distance the kitten ran in 15 seconds=4×15=60 meters
So, the total distance is 90+60=150 meters.
(Alternate method)
Since the two ran in opposite directions, you can add the running speeds of the two and multiply it with time.
(4+6)×15=150 meters
Note: If they ran in the same direction, you would have to find the difference between their running speeds and multiply it with time taken.
