This can be done with just one single number line.

Where is t? Exact middle of 0 and 20; which means, t is at 10.

Brief summary of some values:


Where is u?
.

u is at 15.

Some care with the final question part. This seems to ask for the sum of distance. r to t is 10 units. u to s goes from point 15 to point 20, a distance of 5 units.. The question seems to ask for .
