Enrique leaves his house and starts to run at an average speed of 6 miles per hour. Half an hour later, Enrique's younger (and faster) brother leaves the house to catch up to Enrique running at an average speed of 8 miles per hour. How long will it take for Enrique's brother to run half the distance that Enrique has run?

Question

Enrique ran 3 miles in the half an hour. So it will take 3/8ths of an hour for his brother to run half the distance. I believe it is.... 22.5 minutes
