Question: A train and a boat start from the same point and travel in opposite directions. If the train travels at 80 km/h and the boat at 20 km/h, how far apart will they be after 2 hours?

Options:

  1. 200 km
  2. 160 km
  3. 140 km
  4. 120 km

Correct Answer: 200 km

Solution: 

Distance covered by train = 80 km/h * 2 hours = 160 km. Distance covered by boat = 20 km/h * 2 hours = 40 km. Total distance apart = 160 km + 40 km = 200 km.

Questions & Step-by-Step Solutions

A train and a boat start from the same point and travel in opposite directions. If the train travels at 80 km/h and the boat at 20 km/h, how far apart will they be after 2 hours?
  • Step 1: Identify the speed of the train, which is 80 km/h.
  • Step 2: Identify the speed of the boat, which is 20 km/h.
  • Step 3: Determine the time they travel, which is 2 hours.
  • Step 4: Calculate the distance the train travels in 2 hours: 80 km/h * 2 hours = 160 km.
  • Step 5: Calculate the distance the boat travels in 2 hours: 20 km/h * 2 hours = 40 km.
  • Step 6: Add the distances of the train and the boat to find the total distance apart: 160 km + 40 km = 200 km.
  • Relative Motion – Understanding how two objects moving in opposite directions can be analyzed by calculating their individual distances and summing them.
  • Speed and Distance Relationship – Applying the formula distance = speed × time to find the distance traveled by each object.
