A plane traveled 2464 miles to San Francisco from Boston. With the wind to San Francisco, it took 14 hours. Into the wind from S
an Francisco, back to Boston, the same trip took 16 hours. How fast is the plane traveling when there is no wind? What is the wind speed?
1 answer:
Step-by-step answer:
Given:
Distance = 2464 miles
downwind time = 14 hours
upwind time = 16 hours
Solution:
downwind speed = 2464 / 14 = 176 mph
upwind speed = 2464 / 16 = 154 mph
Average speed = still air speed
= (176+154)/2
= 330/2
= 165 mph
Time required
= 2464 / 165
= 14.933 hours
= 14 hours 56 minutes.
