Question 911487: . 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

You can put this solution on YOUR website! 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
