The speed of the plane will be equal to 240 Mph.
<h3>What is speed?</h3>
Speed is defined as the ratio of the time distance travelled by the body to the time taken by the body to cover the distance.
Given that:-
- Mattie Evans drove 350 miles in the same amount of time that it took a turbo propeller plane to travel 1200 miles.
- The speed of the plane was 170 mph faster than the speed of the car.
The speed of the plane will be calculated as:-
Let the speed of the car will be x mph so the speed of the plane will be
(x + 170)
Now time for the plane:-
Tp = Dp / Sp
Tp = 1200 / (x+170)
Now time for the car:-
Tc = Dc / Sc
Tc = 350 / x
It is given that time taken by both the plane and the car are equal:-
Tp = Tc
1200 / x+170 = 350 / x
1200x = 350x + 59500
850x = 59500
x = 59500 / 850
x = 70mph
The speed of the plane will be calculated By:-
Sp = x + 170 = 70 + 170 = 240 Mph
Therefore the speed of the plane will be equal to 240 Mph.

Step-by-step explanation:
Answer:
rs 38.
Step-by-step explanation:
Total cost of the 80 books = 80*30 = rs 2400.
He had 60 books to sell and made a 5% loss.
Thus his income from these books was 2400 - 0.05*2400 = rs 2280.
So the selling price of each book was 2280 / 60 = rs 38.
Explanation:
It is given than Paul is older than Bill.
Let age of Bill= x years, as x is a natural number.
Then, age of Paul = (x + a) Years, where a is any natural number.
And, Fred is younger than Bill.
So, age of Fred= x - k, where k is any natural number.
So, if we arrange the ages of Fred, Bill and Paul, their ages would be
Fred < Bill < Paul
x-k < x < x+a
Hence, we can say that , Paul is eldest, and Fred is smallest member between three.
