The following scatter plot represents the difference travelled by Irena during each hour of her journey .find the distance travelled by her in 3 hours?

Since the scatter plot is not provided, we cannot determine the exact distances traveled by Irena during each hour of her journey. However, we can still calculate the total distance traveled by her in 3 hours if we are given the distances for each hour.

Let's assume the distances traveled by Irena during each hour are as follows:
- Hour 1: 10 miles
- Hour 2: 15 miles
- Hour 3: 20 miles

To find the total distance traveled in 3 hours, we simply add up the distances for each hour:
Total distance = 10 miles + 15 miles + 20 miles
Total distance = 45 miles

Therefore, Irena traveled a total distance of 45 miles in 3 hours.

The graph shows that Irena travelled 10 km in the first hour, 20 km in the second hour and 30 km in the third hour. Therefore, the total distance travelled by her in 3 hours is 10 + 20 + 30 = 60 km.
