The train went 300 miles in 3 hours; the ___

was 100 miles per hour.
origin
unit rate
coordinate plane

unit rate

The missing term in the statement is "unit rate." The unit rate is calculated by dividing the distance traveled by the time taken. In this case, since the train went 300 miles in 3 hours, the unit rate can be calculated as 300 miles divided by 3 hours, which equals 100 miles per hour.

To find the missing word in the sentence, we can analyze the given information.

We know that the train went 300 miles in 3 hours. To determine the missing word, we need to calculate the speed at which the train was traveling.

To calculate the speed, we can use the formula:

Speed = Distance ÷ Time

In this case, the distance is 300 miles and the time is 3 hours. So we can calculate:

Speed = 300 miles ÷ 3 hours

The result is 100 miles per hour.

Therefore, the missing word in the sentence is "unit rate." The unit rate in this scenario is 100 miles per hour, which represents the speed at which the train was traveling.
