Practicing Success
When the minute hand covers a distance of 1 hr 15 min, then what is the angular distance covered by it? |
430° 450° 480° 192° |
450° |
In one hour, minutes hand covers angular distance = 360° In one minutes, minutes hand covers angular distance = 360°/60 = 6° So, in 1 hours 15 minutes, minutes hand covers = 6°(1 x 60 + 15) = 6° x 75 = 450° |
