Just wanted to say that that the total amount of hours our friend needs to be listened to is 250'000 and not 25'000 as stated in the solution.
It is 15'000'000 / 60 = 250'000

Hi Richard,
Nice catch!
Zeros can be quite tricky and I recommend either using power of ten, or units (M,B,K), OR fully writing out 0s and crossing them out.
Whichever method you find to be the most effective based on how you think through things!
I believe the original question pointed out a direct error in the case. It states the answer to be 25k hours, whereas the correct answer (15m/60 =) is 250k. The case could be corrected, please.
