See how the description fits this table of data and variable assignments.

WHICH           RATE           TIME          DISTANCE
SLOW EARLY       35            t+1/2           d
FAST LATE        45             t              d

You must understand that d is NOT equal to 160, or if it is, you must not assume it to be. This problem description will give ONE equation in only ONE unknown variable, t. You may begin with a system of two equations, but you should derive one single equation from it.
