Best ResponseYou've already chosen the best response.0Answer = 0.8 hours = 48 minutes Relative Speed of Fast plane = 635 mph + 615 mph = 1250 mph Time to 1000 miles = 1000 miles / 1250 miles per hour = 0.8 hours Speed in opposite direction = v1 + v2 Speed in Same direction = v1v2 v1 = speed of fast object v2 = speed of slower object

Best ResponseYou've already chosen the best response.0@Rachel_K You answered correctly above 0.8 hours = 48 minutes. Later you wrote 8 hours and 48 minutes.

Best ResponseYou've already chosen the best response.0Yes, you were, and your explanation above about adding speeds was good. If one plane alone traveling at 635 mph would cover 1000 miles in little more than an hour, then it makes sense that two planes traveling in opposite directions both at 600 something mph would be 1000 miles part from each other in under an hour.

Best ResponseYou've already chosen the best response.0As @Rachael said total speed = 635mph+ 615mph = 1250mph however, to fly 1,000 miles = 1000m/1250mph = 0.8 hours
