[3, 5] is the fastest interval because the average speed is 60 mph
[3, 5] is the fastest interval because the average speed is 63 mph
[5, 9] is the fastest interval because the average speed is 61.1 mph
[5, 9] is the fastest interval because the average speed is 63.4 mph

Answer 1

Based on the given information, it is not possible to determine over which interval the average speed was the fastest. The table does not provide any information about the speed or time spent during specific intervals, making it impossible to calculate the average speed for any given interval.
