A woman traveled 2, 438 miles in 19 hours 20 minutes. Find the average speed of her flight in miles per hour.
*************please show work***************
time = 19 hours 20 min = (19 + 1/3) hrs (20 min = 20/60 hrs = 1/3 hrs)
speed = distance / time
= 2438 / (19 +1/3)
= 2438 / (58/3)
= (2438 * 3) / 58
= 126.1 miles/hr
MPH = (2438) (3) / 58 = 126.1034483
must be a small propellor driven airplane
