i feel like it would be somewhat of a hard equation to set to get the answer. as lazy as i am i would just try the choices for example after 42 min the clock will show 4:29 which 4+2+9=15 so a is not the answer! try all of them and you can find the answer. If you want to find the equation that gives the answer, good luck!
