The Webster family is taking a train to Washington DC. The train travels a constant speed. The train travels 120 miles in 2hrs. At this rate, list the next 4 sets of ordered pairs that represents the distance the train travels for different numbers of hours.

The correct answer is (180 , 3) ; (240 , 4) ; (300 , 5) ; (360 , 6).

Step-by-step explanation:

The Webster family is taking a train to Washington DC.

The train travels 120 miles in 2 hours ≡ (120 , 2).

Speed of the train is 60 miles per hour. ( Speed = )

As the train train travels at constant speed, it will cover 60 miles per hour.

Therefore, the consecutive ordered pairs are given by adding (60 , 1) to the previous ordered pair.

Thus the next ordered pair is given by

(120 , 2) + (60 , 1) = (120+60 , 2+1) = (180 , 3).

Similarly the next three ordered pairs are given by

(240 , 4) ; (300 , 5) ; (360 ,6).
