PART 1.
Going westward:
Distance: 2400 miles
Rate (this is speed): (450-wind_speed) mph
Time: distance / speed = 2400 / (450-wind speed)
Going eastward:
Distance: 2400 miles
Rate (this is speed): (450+wind_speed) mph
Time: distance / speed = 2400 / (450+wind speed)
PART 2
Formula for speed:
speed = distance / time
Now we solve this for time:
time = distance / speed
11h = 2400 / (450+-wind_speed)
+- sign is put because in one case wind increases speed of plane and in other case it decreases speed.
PART 3
To solve for wind_speed we start by rearranging formula so that we have wind_speed on left side:
(450+-wind_speed) = 2400 / 11
(450+-wind_speed) = 218mph
To fly this distance in 11h speed of plane must be 218mph.
The only way to get this solution is if we substract wind speed:
450-wind_speed = 218
wind_speed = 450-218 = 232mph
Answer:

Answer:Answer:
24

26
Step-by-step explanation:
Let's call the smallest integer
n
. Then the next two consecutive integers are
n
+
1
and
n
+
2
.
"Sum of twice the smallest and 3 times the largest is 126"
2
(
n
)
+
3
(
n
+
2
)
=
126
2
n
+
3
n
+
6
=
126
5
n
+
6
=
126
5
n
=
120
n
=
24
So the smallest integer is
24
.
The three consecutive integers are then:
24
,
25
, and
26
.
