Final answer:
The school minibus traveled 320 kilometers.
Step-by-step explanation:
To convert miles to kilometers, we can use the given conversion factor of 1 kilometer equal to 5/8 of a mile. First, we need to find the number of kilometers in 200 miles.
200 miles * (1 kilometer / (5/8) mile) = 200 * 8/5 kilometers = 320 kilometers.
Therefore, the school minibus traveled 320 kilometers.
