Answer 1

Answer: (1) Karen flew 3,000 miles.

We only have information about distance flown by Karen . We have no information of average and max speed .

Not sufficient

(2) Karen flew for 5 hours

We only have information about total time of flight .

Not sufficient

Combining 1 and 2 , we get

Average speed = 3000/5 = 600 miles / hour

We have no information about max speed .

Not sufficient

There are 2 possibilities -

Karen flew at a constant speed of 600 miles per hour throughout the journey .

or She her speed varied across the journey - in this case there might be possibility that her max speed was more than 650 miles per hour
