A jetliner has a cruising air speed of 600 miles per hour related to the air.
00:04
So how long does it take for this plane to fly a round trip from san francisco to chicago and east -west flight, which is 2 ,000 mile each way? it is no wind blowing.
00:15
So if there is no wind blowing, then the time is going to be the total distance over the speed.
00:25
So the total distance is nothing about 2 ,000 each.
00:28
So that's going to be 2 ,000 times 2 .000.
00:30
That's a round trip.
00:30
Or the speed is 600 miles per hour.
00:34
So that's going to come out as let me just grab my calculator.
00:37
So this is coming as 4 ,000 over 600, which is coming as 6 .67 hours.
00:49
And if there's a wind blowing in the part b, there's a wind blowing from west to east, from west to east.
00:56
So if the movement from chicago, from san francisco to chicago is from east, from east to west, this is east and this is west...
