Since we need the average speed in miles per hour we can convert 96 minutes to hours. 96 minutes = 96/60 = 8/5 hours We are also given that the plane completed the remaining 300 miles in t minutes. We must also convert t minutes to hours. t minutes = t/60 hours Now we can calculate the average speed for the entire trip, using the formula for average speed. Average speed = total distance/total time Average speed = (k + 300)/(8/5 + t/60) = (k + 300)/(96/60+t/60) Average speed = (k + 300)/((96 + t)/60) Average speed = 60(k + 300)/(96 + t) Answer: A _________________ Scott Woodbury-Stewart Founder and CEO • Get 300+ Practice Questions 25 Video lessons and 6 Webinars for FREE Available with Beat the GMAT members only code • Award-winning private GMAT tutoring Register now and save up to$200
