A boat covers 132 km
downstream in 3 hours and 96 km upstream in 4 hours. The boat takes 8 hours to travel 'D' km upstream and '2D' km downstream. Find the value of 1.5D .Solution
ATQ,
Downstream speed = 132 / 3 = 44 km/h Upstream speed = 96 / 4 = 24 km/h Now, (D / 24) + (2D / 44) = 8 Or, (11D + 12D) ÷ 264 = 8 Or, D = 96 Required value = 1.5 × 96 = 144
