How to Solve Word Problems of Elapsed Time

A Step-by-step Guide to Solving Word Problems of Elapsed Time

Here’s a step-by-step guide to help you solve word problems involving elapsed time:

Step 1: Read and Understand the Problem

Carefully read the word problem to fully understand what it is asking. Identify the starting time, ending time, and any other relevant information provided.

Step 2: Identify the Knowns and Unknowns

Determine what information is given (knowns) and what information you need to find (unknowns). This will help you organize the problem and set up the solution.

Step 3: Determine the Time Units

Identify the units of time used in the problem. Determine if the problem involves hours, minutes, or a combination of both.

Step 4: Set Up the Problem

Based on the knowns and unknowns, set up the problem mathematically. Determine the operation you need to perform to find the elapsed time.

• To find the elapsed time, subtract the starting time from the ending time.
• To find the ending time, add the elapsed time to the starting time.

Step 5: Perform the Operation

Perform the necessary calculations to find the answer. Make sure to carry over minutes or hours correctly when subtracting or adding time.

Step 6: Check Your Answer

Double-check your calculations and ensure that your answer makes sense in the context of the problem. Verify that the units of time are correct and the answer aligns with the question asked.

Practice solving various word problems involving elapsed time to strengthen your skills. Remember to carefully read the problem, identify the knowns and unknowns, and set up the problem correctly before performing the calculations.
