Answer:
The rate of the jet in still air is 738 mph and the rate of the wind is 90 mph
Step-by-step explanation:
Check: (738+90)*6 = 648*6 = 3888 mike's against the wind
(738-90)*6 = 828*6 = 4968 miles with the wind
5 - 1 = 4 = 2^2
14 - 5 = 9 = 3^2
30 - 14 = 16 = 4^2
55 - 30 = 25 = 5^2
Start with 1, then add 2^2, 3^3, 4^2, 5^2, 6^2, etc.
<h3>
Answer: 43 km per hour</h3>
==================================================
Work Shown:
total distance = 43+40+46 = 129 km
total time = 1+1+1 = 3 hours
average speed = (total distance)/(total time)
average speed = (129 km)/(3 hrs)
average speed = (129/3) (km/hr)
average speed = 43 km per hour
