Why do this problem?

This problem could be used when time, length and distance are being introduced or discussed. It also requires careful thinking to work out how the problem should be tackled.

Key questions

How long would it take Nirmala to get to the market? And how long would it take Riki?
At what time do they want to meet in the market?

Possible extension

Learners could vary the speed or the distance and possibly work out a table of results.

Possible support

Starting by working out how long each one takes to travel the 9 kilometres will help some children. Others may find it useful to draw a sketch map.
