Final answer:
Meteorite A weighs 120 tons, and meteorite B weighs 20 tons.
Step-by-step explanation:
Let's assume the weight of meteorite B is x tons.
According to the given information, the weight of meteorite A is 6 times the weight of meteorite B. So, the weight of meteorite A is 6x tons.
We know that the sum of their weights is 140 tons. So, we can write the equation: x + 6x = 140
Combine like terms: 7x = 140, Divide both sides by 7: x = 20
Therefore, meteorite A weighs 6x tons = 6(20) = 120 tons, and meteorite B weighs x tons = 20 tons.
