Answer:
24 :))))))))))))))
Step-by-step explanation:
2/3 of 48 is 32, so 3/4 of 32 is 24.
against wind the speed = x-y
distance traveled = 2460
2460/x-y= 6
6x-6y= 2460
x-y=410...........1
..
with wind speed = x+y
distance is same 2460
2460/x+y=5
5x+5y=2460
x+y=492............2
..
Add equation 1 & 2
x-y+x+y=410+492
2x=902
x= 451 mph speed of plane in still air.
..
Plug the value of x in equation 1
451-y=410
y=451-410
y=40 mph the speed of wind

Ok you wash 38 in 2 hours
now multiply 38 by 3 and that's the total you wash in 6 hours
( the 3 is the amount of 2 hour shifts total)
finally divide 38 by 2 and then add that to the total you wash in 6 hours
Answer:
7 Months
Step-by-step explanation:
x=number of months
how much is deducted total=number of months times amount deducted per m onth
amount deducted per month=45
number of months=x
how much deducted total=45x
460-deducted total is more than 100
460-45x>100
solve for x
add 45x to both sides
460>100+45x
subtract 100
360>45x
divide both sides by 45
8>x
answer is 7 months
if he does 8 months, then he will have exatly 100 and 100 is noe more than 100
