Question 70274
you are driving on a highway to a town that is 300 kilometers from your home.after 30 minutes you pass a free way exit that you know is 50 kilometers from your home.Assuming that you continue at the same constant speed, how long will it take for this entire trip?

----------
(300-50)km/30 minutes = 50/x minutes
x = 30*50/250
x = 6 minutes
