How to use upper and lower bounds.

This video is around grade A GCSE and deals with the question:

The distance is 26.2 miles correct to 3 significant figures. The time is 3.1 hours correct to 1 decimal place.

Calculate the least possible value for Sarah's average speed. Give your answer correct to 2 decimal places."
