two planes leave chicago at 1 p.m. Plane A heads east at 500 m/h and Plane B heads due west at 600 m/h, how long does it take for the planes to be 6600 miles apart?
Answer provided by our tutors
let
t = the time of the travel
since distance = speed*time and the planes travel in opposite directions we have
500t + 600t = 6600
by solving we find
t = 6 hr
