Two trains each 50 m long are travelling along a train track. What is the length of the track that they occupy at any given time?

  • Answer

    100 m

  • Explanation

    If the length of a train is 50m, then the length of track that the train travels on must also be 50m. If there are two trains, each 50m long, then the sum would be:
    50 + 50 = 100
    The two trains occupy 100 m of track at any given time.

A car travels on a straight track for 3 hours. It stops to fill up with gas for 30 minutes. It starts driving again and drives for another 2 hours before it gets a flat tyre. It takes 30 minutes to fix the tyre and start driving again. The car drives another 2 hours before it finally arrives at its destination. How long did the entire journey take, including the stops?

    8 hours

  • Explanation

    To make it easier, add each amount separately:
