Two particles are projected simultaneously towards each other from opposite ends of a straight horizontal tube. One particle travels 97 cm in the 1st 2 seconds, 93 cm in next 2 seconds , 89 cm in

another next 2 seconds, etc. The other particle travels 49 cm in the 1st 2 seconds, 47 cm in the next 2

seconds , 45 cm in another next 4 seconds, etc. Find how long it takes for the particles to meet and

hence, determine the distances travelled by each particle.

The problem with this question is that it is missing an important number, which is the length of the tube. Assuming that the tube is 10 meters long (=1,000 centimeters long)

                                                                                              particles in cms

1                               97                            49                     854

2                               93                            47                     714

3                               89                            45                     580

4                               85                            43                     452

5                               81                            41                     330

6                               77                            39                     214

7                               73                            37                     104

8                               69                            35                     0

After 8 seconds both particles should meet. Particle A traveled 664 centimeters and particle B traveled 336 centimeters.    

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
