RE: A plane moves from 9ËšN40ËšE to 9ËšN40ËšW. If the plane starts at 10 am and takes 8 hours to reach the destination, find the local arrival time
40deg E to 40deg west. first add the deg 40+40 80. for 1 deg 4min so 80deg 80*4 320 5hrs20min arriving time starting time+hrs of journey -5hrs20min. minus(-) is used becoz the direction is from east to west. so 10+8-5hrs20min 12.40pm
