An insect can walk in both forward and reverse directions. He walks forward for 3 minutes and then reverse for 2 minutes. He walks at the speed of 5 meters per minute. In what minimum time will he be able to cover 105 metres?
Explanation:
In one 5-minute cycle, the insect walks 15m forward and 10m reverse, yielding a net progress of 5m per cycle. After 18 cycles (90 minutes), it has advanced 90m. In the next 3 minutes, it walks continuously forward at 5m/min, covering 15m. 90m + 15m = 105m. Total time = 90 + 3 = 93 minutes.
The question below consists of two statements I and II. You have to decide whether the data provided in the statements are sufficient to North the question. Read both the statements and choose the correct option.
Question: In which direction is L with respect to K?
(I) R is west of P and north of K.
(II) P is north-west of L and south-west of M.
A.The facts in both the statements I and II together are sufficient to North the question.
B.The data in statement I and II together are not sufficient to North the question.
C.The facts in statement II alone are sufficient to North the question.
D.The facts in statement I alone are sufficient to North the question.
Explanation:
Statement I tells us K is South of R, and P is East of R. Statement II tells us L is South-East of P. Combining both, K and L are both located generally South of P, but their exact lateral distances are unknown, making it impossible to determine the precise angle/direction of L with respect to K.
