Question
Vishnu travelled equal distances at speeds of 10 km/hr.,
30 km/hr., and 8 km/hr., and took a total of 15.5 minutes to complete. Find the total distance he travelled, in km.Solution
Let the distance be D km According to the question, D/10 + D/30 + D/8 = 15.5/60 (12D + 4D + 15D)/120 = 15.5/60 31D/120 = 15.5/60 D = (15.5 x 120)/(60 x 31) D = 1 km So, the total distance = 1 + 1 + 1 = 3km

ZFKQ, BCMN, ?, FWQH, HTSE
