Question

HELPP!! Two airplanes leave an airport at the same time. the first airplane flies east at 635mph. the second airplane flies west at 615mph. how long will it take for the airplanes to be 1,000 miles apart?

Answer 1

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
