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.
The height of a dartboard is 150 cm from the floor to the bottom of the dartboard. If the dartboard is 46 cm wide and there is still another 48cm from the top of the dartboard to the ceiling, how high is the wall?
To make it easier, do each equation separately.
Kerry: 3 marbles
Sarah: 3 marbles + 5 marbles = 8 marbles
Joseph: 8 marbles + 12 marbles = 20 marbles
Tuli: 20 marbles + 6 marbles = Tuli has 26 marbles
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.
