Tom reads at an average rate of 30 pages per hour, while Jan reads at an average rate of 40 pages per hour. If Tom starts reading a novel at 4:30, and Jan begins reading an identical copy of the same book at 5:20, at what time will they be reading the same page?

(A) 9:30
(B) 9:00
(C) 8:40
(D) 7:50

Tom reads 30 pages per hour... = 0.5 pages per minute = 5 pages in 10 mins.

So given that he has a 50 min head start.

He will read 50*0.5 = 25 pages before Jan starts

So at 5:20 T = 25, J = 0
6:20 T = 55, J = 40
7:20 T = 85, J = 80
8:20 T = 115, J = 120

Ok so Jan overtook Tom... so the value has to be between 7:20 and 8:20. There is only one value that is so .. So D
