Either look online for a similar problem or just make one up yourself using the example already given. There are plenty of online versions of solved "work problems". YouTube is a pretty good resource for this.

If you call the two different times for completing the task x and y a general equation for solving all times can be written like this:$$x*y/(x+y)$$
For the lawn mowing problem this gives us $$2*4/(2+4)=8/6=1.333...=1 hour 20 minutes$$
