Homework Statement

A droplet of oil is placed at the bottom of a circular container of radius(R)= 50m so that it is in the centre. If the radius (r) of the droplet is increasing at a constant rate of 0.5ms^-1. How long will it take for the droplet to reach the sides of the container i.e.when R=r.

Homework Equations

T=x/y=R/r where T=time, x=radius of container, y=radius of droplet.

The Attempt at a Solution

t=50/0.5=100s?

I don't do maths so I thought maybe you guys could help.

Thanks a lot.

If you walk a half a meter per second how far will you go in 1, 10, and 100 seconds?

.5m, 5m, 50m ?

You don't do math, you just did math!
