Question

A girl was travelling in a boat, suddenly wind starts blowing and blows her har and started floating back downstream. The boat continued to travel upstream for 12 more minutes before she realised that her hat had fallen off.she turned back downstream and she caught her hat as soon as she reached the starting point.If her hat flew off exactly 2 km from where she started.what is the speed of the water

Answer 1

Answer:

27.77 m/s

Step-by-step explanation:

Time= 12 min = 12*60 sec

Distance= 2 km = 2*1000 m

Speed= Distance÷Time

= (12*60) ÷ (2*1000)

= 27.77 m/s

Answer 2

5 $kmhr^{-1}$ is the Answer

Step-by-step explanation:

Given,  

Distance traveled, d = 2 km

Time is taken after hat chase = 2 $\times$ 12 = 24 minutes

Let's convert the times from minutes into hours,  

we know that the unit for time with distance in kilometers is hours.

So, $24 \times \frac {1}{60} = \frac {2}{5}$ hours (We know that 1 hour has 60 minutes)

Hence, $Speed = \frac {Distance\ travelled}{Time\ Taken}$

= $\frac {2}{\frac {2}{5}}$

= 5 $kmhr^{-1}$
