The speed of plane is 105 miles per hour and speed of wind is 28 miles per hour.
Step-by-step explanation:
Given,
The distance traveled by plane = 1463 miles
The trip with the wind took 11 hours.
The trip took 19 hours against the wind.
Let,
s be the speed of plane and w be the speed of wind.
Therefore;
Speed with the wind = s+w
Speed into the wind = s-w
We know that;
Distance = Speed * Time
Therefore;
Equation for trip taken with wind.
1463 = 11(s+w)
Dividing both sides by 11

Equation for trip taken into the wind
1463 = 19(s-w)
Dividing both sides by 19

Adding Eqn 1 and 2

Dividing both sides by 2

Putting s=105 in Eqn 1

The speed of plane is 105 miles per hour and speed of wind is 28 miles per hour.
Answer:
80 children attend this day care,
Step-by-step explanation:
Let x represent the number of children that attend this day care center. The day care worker found 28 children absent one day during an epidemic of chicken pox.
If this was 35% of the total number of children attending the day care center, it means that the number of children absent one day during the epidemic of chicken pox can be expressed as
35/100 × x = 0..35×x = 0.35x
Therefore,
0.35x = 28
x = 28/0.35= 80
