1.	A boat which has a speed of 12 m/s in still water crosses a river of width 60 m in minimum possible time. Total distance covered by the boat, will be (Velocity of water in river = 5 m/s)
Answer» $t = 60/Vbr$ = 60/12 = 5 s x = Vr ×t = 5× 5 d = √(60)² + (25)² = 65 cm please MARK me brain mark list

Answer»

$t = 60/Vbr$

= 60/12

= 5 s

x = Vr ×t

= 5× 5

d = √(60)² + (25)²

= 65 cm

please MARK me brain mark list
