Question

A tourist group with 5 people uses the water that they took over 14 days. Two more join in. How many days would it take for the water to finish ?

Answer 1

How long would the water last now?

Answer 2

Use this equation: 14*5/7

=10.

It would take a tourist group of 7 people 10 days to finish the water.
