Each hour the train got closer to Kansas City. In the first hour, it traveled 54 miles. In the first three hours it traveled 209 miles. In the third hour it traveled 82 miles. Therefore, during the second hour it must have traveled Answer
miles.

73

Step-by-step explanation:

Setting Up An Equation

The question provides the distances the train traveled in the first 3 hours

T = total distance

A = distance during 1st hour

B = distance during 2nd hour

C = distance during 3rd hour

the total distance traveled is equal to the sum of the distances of the first three hours so our equation would be

T = A + B + C

Solving For B

Since the question asks for the distance during the second hour, we need to find B

It is already given that A = 54, C = 82, and T = 209, so plug in the values and solve for B

T = A + B + C

B = T - A - C

B = 209 - 54 - 82

B = 73

Final Answer

B = 73

6 hours 48 min
