A person travels equal distances with speeds of 2km/hr, 6km/hr, 6km/hr. and takes a total time of 11minutes. Find the total distance ? Choose one.
A) 1 km B) 500 mts C) 660 mts D) 2 km E) 250 mts

Rationale: "let the each distance be x km total distance = 3 x then total time , ( x / 2 ) + ( x / 6 ) + ( x / 6 ) = 11 / 60 x = 0.22 total distance = 3 * 0.22 = 0.66 km = 660 meters correct option is c"
Answer: C
