"Sensible," she declares, nodding as she reviews his equations. "Here--"
Without thinking, Matilda gives the pencil a look, tugging it telekinetically out of his grip so she can pluck it out of the air and add in a few numbers here and there.
"If we want to make a good estimate of the distances we're traversing, providing we're planning to walk for a while of course - and I see no reason why we shouldn't; goodness knows there doesn't appear to be anything here worth staying for - we should make an estimate of our average walking speed somehow and record our time of departure." Scribblescribble. "You have a watch; I've got a ruler if we want to try for a more precise estimate. Or we could try a calculation by average stride length and steps per minute. Which d'you think would be more efficient?"

This applied mathematics thing is fun!
