Find the correct relationship between the given quantities:\ Speed of a boat in still water is 12 km/hr. \ Quantity I: time taken by boat to go 28 km in still water. \ Quantity II: time taken by boat to go downstream 32 km in stream speed of 4 km/hr.
-
Quantity II > Quantity I
-
Quantity I ≥ Quantity II
-
Quantity I > Quantity II
-
Quantity I ≤ Quantity II
-
Quantity I = Quantity II
C
Correct answer
Explanation
Quantity I: Speed = 12 km/hr, distance = 28 km. Time = 28/12 = 7/3 ≈ 2.33 hours. Quantity II: Downstream speed = 12 + 4 = 16 km/hr, distance = 32 km. Time = 32/16 = 2 hours. 2.33 hours > 2 hours, so Quantity I > Quantity II.
