I. Design a program using flowgorithm that calculates and displays the number of miles per hour over the speed limit that a speeding driver was doing. The program should ask for the speed limit and the driver's speed. Valid the input as follows:

$1.$ Speed limit should be at least $20,$ but not greater than $70.$

$2.$ The driver's speed should be at least the value entered for the speed limit $($otherwise the driver was not speeding$).$

Once correct data has been entered, the program should calculate and display the number of miles per hour over the speed limit that the driver was doing.

II$.$Write a program using flowgorithm that computes for the average of scores of a student. Scores accepted must be between $0$ to $100.$

Sample console:

Enter test scores from $0$ to $100.$

To end the program, enter $-1.$

Enter score: $90$

Enter score: $80$

Enter score: $150$

Score must be from $0$ to $100.$ Try again.

Enter score: $75$

Enter score: $-1$

$$

Score count: $3$

Score total: $245$

Average score: $81\mathrm{.}6667$
