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.
A soldier walks 2 km towards north, then he turns left and walks 3 km, again he turns left and walks continuously. In which direction is he walking now?
