Bill and Harry are practicing for a track meet. Last week, Bill ran 900 meters on each of 3 days. Harry ran 1.2 kilometers on each of 2 days.

Between last week and this week, Bill wants to run a total of 6 kilometers. How far does Bill need to run this week?

900 * 3 = 2,700 meters = 2.7 km

6 - 2.7 = ________ km

3.3

4.7

To find out how far Bill needs to run this week, we need to determine the distance he has already run last week and subtract it from the total distance he wants to run this week.

Last week, Bill ran 900 meters on each of 3 days. So the total distance he ran last week can be calculated by multiplying the distance he ran on each day (900 meters) by the number of days (3):
Total distance Bill ran last week = 900 meters x 3 = 2700 meters.

Since we want to find out how far Bill needs to run this week, we subtract the distance he has already run from his goal of 6 kilometers (which can be converted to meters for consistency):
Distance Bill needs to run this week = 6000 meters - 2700 meters = 3300 meters.

Therefore, Bill needs to run 3300 meters this week to reach his goal.
