<u>Answer:</u>
The driver should travel at a Speed of 50 mph so that the average speed of the entire trip is 45 mph
<u>Step-by-step explanation:</u>
Given:
Total distance=100 mi
Speed at which the driver travels the first 50 mi= 40 mph
To Find:
Speed at which the driver should travel so that the average speed of the entire trip is 45 mph=?
Solution:
Average speed:
The average speed of an object is the total distance travelled by the object divided by the elapsed time to cover that distance. It's a scalar quantity which means it is defined only by magnitude. A related concept, average velocity, is a vector quantity. A vector quantity is defined by magnitude and direction.
Let X be the distance at which driver should travel so that the average speed of the entire trip is 45 mph
From The given data we get,
X=50
5+2w=l
2w+2l=130
2w+2(5+2w)=130
2w+10+4w=130
6w=130-10
w=120/6=20
l=5+2•20=45
Area=20•45= 900inches^2
