Two particles are projected simultaneously towards each other from opposite ends of a straight horizontal tube. One particle tra
vels 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 2 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)

1 97 49 854
2 93 47 714
3 89 45 580

After 8 seconds both particles should meet. Particle A traveled 664 centimeters and particle B traveled 336 centimeters
A certain map scale in which 1/2 inch on the map represents an actual distance of 10 miles. A distance of x miles is represented by how many inches on this map?
