Answer:
s = 45 m
Explanation:
The velocity given in the question is uniform. Hence, the formula for the uniform velocity shall be used here. The formula is given as follows:

where,
s = distance traveled away from the brother = ?
v = constant speed = 3 m/s
t = time taken = (0.25 min)(60 s/1 min) = 15 s
Therefore, using these values in the formula we get:

<u>s = 45 m</u>
The correct option is D.
Because <span>the distance that the honey flows is a dependent variable. Becuase the coefficient of viscosity is dependent on the velocity gradient (v/L). And, </span>Viscosity is very temperature dependent • It decreases with increasing temperature (in case of liquids). But, Viscosity of a gas increases with increasing temperature.
