t is the time to catch up (Wendy's time)
... she catches up when they have traveled the same distance
... his travel time is two hours longer
20 * (t + 2) = 28 * t
Wilfred and Wendy have a long distance bike race. Wilfred rides at 20km/h and has a 2 hour head start. Wendy travels at 28 km’h. How long does it take for Wendy to catch up to Wilfred?
