Problema Solution
Two trains are traveling toward each other on adjacent tracks. One of the trains is 220 feet long and is moving at a speed of 40 miles per hour. The other train is 180 feet long and is traveling at the rate of 60 miles per hour. Find the time interval between the moment the trains first meet until they completely pass each other. (1 mile=5280 feet)
Answer provided by our tutors
so relative speed of train is 60+40=100 mile per hour
now 1 mile=5280 feet
so train relative speed= 100*5280feet per hour = 528000 feet per hour
nowtrain relative distance is 220+180=400
so time taken = 400/528000 hour = 4/5280 hour = 4.77 seconds
