Mina wore a pedometer on her foot for 3 hours. She recorded the number of steps she walked for each hour. The first hour she took 2,387 steps. The second hour she took 3,872 steps. If she took a total of 9,245 steps, about how many steps did she take on the third hour

Mina took 2,986 steps on the third hour.

Step-by-step explanation:

With the information provided, you know that Mina took a total of 9,245 steps in three hours and as you know the quantity of steps she took on the first and second hour, you can subtract the steps she took on the first and second hour from the total amount of steps to determine the steps she took on the third hour:

9,245-2,387-3,872=2,986

According to this, the answer is that Mina took 2,986 steps on the third hour.
