Answer 1

Answer:

a)6.4 kms

Step-by-step explanation:

Speed of boat in still water = 12 kmph

Speed of stream = 4 kmph

Total Speed = 12+4

                     = 16 kmph

Time = 24 minutes

         = $\frac{24}{60}$ hours

         = $\frac{2}{5}$ hours

         = 0.4 hours

Distance = Speed x Time

               = 0.4 x 16

               = 6.4 kms
