Module 6: Lesson 4

What are the three key components often found in time word problems?

• Start time, end time, break time

• Start time, elapsed time, finish time

• Elapsed time, break time, finish time

• Start time, break time, finish time

How do you find the start time if you know the finish time and the elapsed time?

• Divide the finish time by the elapsed time

• Multiply the elapsed time by the finish time

• Subtract the elapsed time from the finish time

• Add the elapsed time to the finish time

If the finish time is 4:40 and the elapsed time is 28 minutes, what is the start time?

• 4:15

• 4:30

• 4:20

• 4:12

What should you be careful about when using a number line to solve time problems?

• Using a digital clock

• Counting seconds

• Switching between hours

• Adding instead of subtracting
