Velocity (against wind) = 2,688 km / 4 hr = 672 km/hr
Velocity (with wind) = 3,208 km / 4 hr = 802 km/hr
psa means plane velocity in still air
ws means wind speed
psa -ws = 672
psa +ws = 802 We add both equations and get
2 psa = 1,474
plane velocity (in still air) = 737 km/hr

psa +ws = 802 so that means

wind speed = 802 -737 = 65 km/hr

Answer: $531.51

Step-by-step explanation:

Initial balance of 500

If he made deposits into his account that means he added to his existing balance so his new balance would be the initial 500 plus all the deposits:

500 + 100 + 250 + 300 = 1150

so after the deposits he has a new balance of 1150. He then withdrew money which means he's subtracting from his balance so his new balance will be his current balance minus all the withdraws:

1150 - 400.32 - 100 - 55.55 - 62.62 = 531.51
