Walking at 6/7 of his typical speed, a clerk reaches his documentation terminal 14 minutes late. What is his typical time?
Correct Answer: Option D
Explanation:
New speed = 6/7 of typical speed => New time = 7/6 of typical time. Difference = 1/6 of typical time = 14 minutes. Typical time = 14 * 6 = 84 minutes.
New speed = 6/7 of typical speed => New time = 7/6 of typical time. Difference = 1/6 of typical time = 14 minutes. Typical time = 14 * 6 = 84 minutes.

A standard boat can row 12 km/h in still water. If the speed of the current is 2 km/h, find the time required to log 30 km upstream.
Correct Answer: Option B
Explanation:
Upstream speed = 12 - 2 = 10 km/h. Time required = Distance / Upstream speed = 30 / 10 = 3 hours.
Upstream speed = 12 - 2 = 10 km/h. Time required = Distance / Upstream speed = 30 / 10 = 3 hours.

A bicycle wheel of diameter 140 cm makes 300 revolutions in one minute. Find the speed of the bicycle in km/h.
Correct Answer: Option C
Explanation:
Radius r = 70 cm = 0.7 meters. Circumference = 2 * (22/7) * 0.7 = 4.4 meters. Distance in 1 minute = 300 * 4.4 = 1320 meters. Distance in 1 hour = 1320 * 60 = 79200 meters = 79.2 km. Speed = 79.2 km/h.
