Jane: 50 + 4d
Ellis: 24 + 6d
4d + 50 = 6d + 24
Jane: (6d + 24) - 4d = 50 + 2d
Ellis: (6d + 24) - 6d = 24
Both: 50 + 2d

The robot tutor actually started off quite well, but then messed up
after d days, Jane will have 4d + 50 , (the robot had that)
after d days, Ellis will have 6d + 24 , the robot had that too
how long before the have the same ?
6d + 24 = 4d + 50 , the robot even had that, but then totally messed up ....
2d = 26
d = 13
so it will take 13 days for them to have the same, and that will
be 4(13) + 50 = 102
or, we could find Ellis' which must be the same ...
6(13) + 24 = 102
