Answer:
2225 km
Explanation:
since he travels 89 km per day, works 5 days per week, and it asked how many km he has to travel in 5 weeks, the equation should be 89*5*5, which is 2225 km. In this case, 89 represents the km he travels every day, 5 represents the days he has to work per week, and the other 5 represents the times of the week.
