Two trains are travelling towards each other from 200 miles apart on the same track: Train A travels at 30 miles per hour, Train B travels at 70 miles per hour. At the same time, a robotic bee buzzes back and forth between the trains at a speed of 150 miles per hour. How far will the bee travel, in total, before the trains collide
Two trains are travelling towards each other from 200 miles apart
Train A travels at 30 miles per hour,
Train B travels at 70 miles per hour.
travelling towards each other so combined speed = 70+30 = 100 mph

t=d/r
Time taken by trains to meet = 200/100 = 2 hours
a robotic bee buzzes back and forth between the trains at a speed of 150 miles per hour.
D= r*t
= 150*2 = 300 miles

the bee will travel 300 miles , before the trains collide
