A wheel makes 1000 revolutions to cover a distance of 880 meters. Find the diameter of the wheel.
Correct Answer: Option B
Explanation:
Distance covered in 1 revolution = 880 / 1000 = 0.88 meters = 88 cm. Circumference = 2 * (22/7) * r = 88 cm => (44/7) * r = 88 => r = 14 cm. Diameter = 2r = 28 cm.
Distance covered in 1 revolution = 880 / 1000 = 0.88 meters = 88 cm. Circumference = 2 * (22/7) * r = 88 cm => (44/7) * r = 88 => r = 14 cm. Diameter = 2r = 28 cm.

A train 130 meters long passes a platform 270 meters long in 20 seconds. Find the speed of the train in km/h.
Correct Answer: Option A
Explanation:
Total distance = 130 + 270 = 400 meters. Speed = 400 / 20 = 20 m/s. In km/h = 20 * (18/5) = 72 km/h.
Total distance = 130 + 270 = 400 meters. Speed = 400 / 20 = 20 m/s. In km/h = 20 * (18/5) = 72 km/h.

A cyclist rides from his village to town at 16 km/h and returns at 12 km/h. If the entire journey takes 7 hours, what is the distance from the village to the town?
Correct Answer: Option B
Explanation:
Let distance be d. d/16 + d/12 = 7 => (3d + 4d) / 48 = 7 => 7d / 48 = 7 => d = 48 km.
