paper boat in place it ib the river. She allows the paper boat to flow for a
distance of 20 m. She notices that boat takes 40 seconds to cover 20m.
Calculate the speed of river flow.​

Answer 1

Dear Students,

● Answer -

v = 0.5 m/s

◆ Calculation -

# Given -

s = 20 m

t = 40 s

# Solution -

Speed of the paper boat is given by -

Velocity = distance / time

v = s / t

v = 20 / 40

v = 0.5 m/s

Therefore, Speed of the river flow will be 0.5 m/s.

Hope this helps you. Thanks for asking..
