While Leslie flying his airplane from Hartfield to Weatherford, did he ever fly faster than 200 miles per hour?
1) The distance from Hartfield to Weatherford is 470 miles.
2) The flight from Hartfield to Weatherford took Leslie exactly 2 hours.
The OA is C.
Neither data 1 nor data 2 is sufficient but combing 2 data is sufficient.
From statement 1, we get the total distance.
From statement 2, we get the total time.
Then, combining 1&2 we can find the speed
Speed = Total Distance / Total time = 470 / 2 = 235 mph. Which is greater than 200 mph.
Has anyone another strategic approach to solving this DS question? Regards!
