Answer
The most appropriate data type of the variable seconds is an Integer or Int. This is because seconds represents a count of time, which is inherently a whole number.
Step 2

Answer
rest could have been defined as a constant because its value (50) does not change throughout the execution of the algorithm. Since it is initialized and not modified during the algorithm's operation, defining it as a constant would enhance clarity and mean it can't be accidentally altered.
Step 3
