Best ResponseYou've already chosen the best response.0You use the formula d = rt So for the first part of the trip 6 = 4t because we know the rate is 4 but we don't know how long it took. If you divide both sides by 4 you will get 1.5 = t The second part is 6 = 3t because we know the rate is 3 but we don't know how long it took. If you divide both sides by 3 you will get 2 = t. So it took you 1.5 hours for the first half and then 2 hours to get back fo a total of 3.5 hours.
