Q
Q: Two trains are moving towards each other at speeds of 60 km/h and 90 km/h. If they are 300 km apart, how long will they take to meet?
Solution:
Relative speed = 60 + 90 = 150 km/h. Time = distance/speed = 300/150 = 2 hours.
Steps: 6
Show Steps
Step 1: Identify the speeds of the two trains. Train 1 is moving at 60 km/h and Train 2 is moving at 90 km/h.
Step 2: Calculate the relative speed of the two trains by adding their speeds together: 60 km/h + 90 km/h = 150 km/h.
Step 3: Determine the distance between the two trains, which is given as 300 km.
Step 4: Use the formula for time, which is time = distance / speed.
Step 5: Plug in the values: time = 300 km / 150 km/h.
Step 6: Calculate the time: 300 divided by 150 equals 2 hours.
