Answer:
4 more laps to reach the goal of 14.4 km.
Explanation:
First, let's find the total distance covered so far: 720 m x 16 laps = 11,520 m.
Next, let's convert the goal distance to meters: 14.4 km x 1000 m/km = 14,400 m.
Finally, let's subtract the total distance covered from the goal distance to find the remaining distance: 14,400 m - 11,520 m = 2,880 m.
Since a lap is 720 m long, the remaining distance can be divided by 720 m to find the number of laps left: 2,880 m ÷ 720 m = 4 laps.
Therefore, the runner needs to run 4 more laps to reach the goal of 14.4 km.
