A missile travels at a speed of 1440 km/h. Find the distance covered by the missile in exactly 12 seconds.
Correct Answer: Option A
Explanation:
Speed in m/s = 1440 * (5/18) = 80 * 5 = 400 m/s. Distance covered in 12 seconds = Speed * Time = 400 * 12 = 4800 meters.
Speed in m/s = 1440 * (5/18) = 80 * 5 = 400 m/s. Distance covered in 12 seconds = Speed * Time = 400 * 12 = 4800 meters.

A man starts walking from a place P at 4 AM at a speed of 5 km/h. Another man starts from the same place P at 6 AM in the same direction at a speed of 7 km/h. At what time will they meet?
Correct Answer: Option A
Explanation:
By 6:00 AM, the first man has traveled for 2 hours, covering 5 * 2 = 10 km. Relative speed = 7 - 5 = 2 km/h. Time to meet = 10 / 2 = 5 hours. Meeting time = 6:00 AM + 5 hours = 11:00 AM.
By 6:00 AM, the first man has traveled for 2 hours, covering 5 * 2 = 10 km. Relative speed = 7 - 5 = 2 km/h. Time to meet = 10 / 2 = 5 hours. Meeting time = 6:00 AM + 5 hours = 11:00 AM.
