Question

in python
You're always in a hurry and worried about missing your classes. However, you are afraid to get speed tickets in case you exceed the speed limit on the road if you leave late from home or work.
Therefore, you need to drive at the maximum speed allowed and make sure to reach your class on time.
For this purpose, you need to write a program that will read from the user the maximum speed
limit (assume it is the same across all roads) and the distance to be traveled (in KM) and then
print the time (in hours and minutes) at which they will have to leave home or work. You may
also assume that you'll maintain a constant speed till you arrive.
You may use any built-in function that can help you with that.
Example:
If the maximum speed limit is 80 km/hr and you're 20 km far from the university and your class starts at 2:00 pm then you need to leave your work or home at maximum at 01:45 pm since it takes you 15 minutes to arrive.

Answer 1

thanks for the question, here is the python program.

==================================================================

def main():
    # assuming the class starts at 2:00 pm every day
    # tracking the time in military hours and mins
    class_hrs = 14
    class_mins = 0

    max_speed_limit = int(input('Enter maximum speed limit (km/hr): '))
    distance = int(input('Enter how far is your university (km): '))

    minutes_needed = (distance * 60) // max_speed_limit

    time_to_leave = class_hrs * 60 + class_mins - minutes_needed
    hours = time_to_leave // 60
    mins = time_to_leave % 60

    if hours>=12:
        print('You must leave at max by {:02d}:{:02d} p.m'.format(hours-12,mins))
    else:
        print('You must leave at max by {:02d}:{:02d} a.m'.format(hours,mins))
main()
