Answer to Question #273228 in Python for Shiny

Question

1. Time measurement using song duration

Consider that Alice is cycling from point A to point B. During the cycling, Alice is listening to songs in her music player.

Given the following inputs:

1. The distance between A and B in metres

2. The speed at which Alice is traveling in metres per second

3. Duration of each song in her playlist in the

following format: mm:ss

the program should:

• Print the number of the song that Alice is listening when the cycling is completed from A to B

· Print Invalid input if any of the constraints mentioned in the constraints section is violated

Example 1

Consider the following inputs:

2000

5

Now consider the following list of songs:

05:30

02:04

Answer 1

dis = int(input())
speed = int(input())
time = dis / speed
cnt = 0
bar = 0
l = list(map(str, input().split()))
ll = []
for i in l:
    foo = int(i[:2])*60+int(i[3:])
    ll.append(foo)
for i in ll:
    cnt += i
    bar +=1
    if cnt >= time:
        print(bar)
        break
