An airplane takes three hours to travel a distance of 1320 miles with the wind the return trip takes four hours against the wind find the speed of the plane in still air and the speed of the wind

106.6 mi/h,    26.6 mi/h

Step-by-step explanation:

PRIMERO SE CALCULA LE VELOCIDAD CON EL VIENTO QUIETO

v = = 106.6 mi/h

DESPUÉS SE ENCUENTRA LA VELOCIDAD DEL AVIÓN EN CONTRA DEL

VIENTO

v = = 80 mi/h

FINALMENTE SE ENCUENTRA LA VELOCIDAD DEL VIENTO

v = 106.6 mi/g - 80 mi/h = 26.6 mi/h

Step-by-step explanation:

principal (P)=15000

rate (T)=1.5%

time (R)=10 years

first lets find interest

Interest=PTR/100

=15000*1.5*10/100

=225000/100

=2250

Now total amount he gets after 10 years at the reate of 1.5% is

Amount = Principal + Interest

=15000 +  2250

=17250

Therefore he gets 17,250.
