Question

Tatiana practiced a total of 12 hours last week to prepare for her gymnastics meet. The line plot shows how long she practiced on the first six days of the week. If Tatiana practiced every day last week, how long did she practice on the last day?

Answer 1

To find out how long Tatiana practiced on the last day, subtract the total practice time for the first six days from the total practice time for the week.

Step-by-step explanation:

To find out how long Tatiana practiced on the last day, we need to calculate the total practice time for the first six days of the week. Looking at the line plot, we can see that each mark represents 1 hour of practice time. So, the total practice time for the first six days is 5 hours.

Since Tatiana practiced a total of 12 hours last week, we can find out how long she practiced on the last day by subtracting the total practice time for the first six days from the total practice time for the week:

Total practice time for the last day = Total practice time for the week - Total practice time for the first six days

Total practice time for the last day = 12 hours - 5 hours = 7 hours.
