Answer = 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 = v1-v2 v1 = speed of fast object v2 = speed of slower object
so 48 minutes?
its bout flieing so how can it be 48 minutes? :/
start with the basics : speed = distance/time
Draw yourself a diagram.
thats what i got :b
i didn't i explained in the beginning im just confirming what i got
ok then so i was right
Yes, 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.
