Answer:
The answer is 118 laps.
Explanation:
First you would have to add 89 + 147 to find how many laps Hans ran over the summer.
Then you have to divide the answer from 89 + 147 by 2 which is 236 divided by two because Hans' laps were twice as much as lee's do when you do 236 divided by 2 you get 118. So, Lee ran, and swan 118 laps.
