Got C also. This problem is clearly about the Pythagorean theorem
First, just find the ground distance between the current position and the re-routed position:
distance = (15^2 + 8^2 )^1/2 = 289^1/2

Actual distance between current position and re-routed position:
distance = (289^1/2 + 6^2)^1/2 = 325^1/2 = 5 * 13^1/2

Actual distance between current position and original position:
distance = (8^2 + 6^2)^1/2 = 100^1/2 = 10

Speed differential in order to arrive on time:
Distance/Time = Speed
NB Time is 1/20 because 3minutes = 1/20 hour
= (5 * 13^1/2 - 10) / (1/20)
= 20 * (5 * 13^1/2 - 10)
= 100 * SQR13 - 200

I think you did the problem correctly upto certain point but than what the question is asking is "By how many miles per hour pilot has to increase the speed? "

What you found is I think "What should be the speed of plan to reach the new destination on time?"

Hi Geethu,

You calculated the speed necessary to land at 8 PM. But the question is asking the increase in the speed.
