Answer: 9 seconds
Explanation:
so first of all,we have to convert their minutes to seconds because the question is asking about seconds.
since 1 minute equal 60 seconds, we will multiply their minute by 60.
Randy 6.2 * 60 = 372
Leslie 6.35 * 60= 381
381 - 372= 9 which means it took Leslie 9 seconds longer to run the mile than it took Randy.
