Anybody can i need it by today at 4 pm

Let's define our time dimension as t=0 in minutes at 9 AM. This means that Andy leaves at t=0 and Bernard leaves at t=330 (2:30PM is 5.5 hours later, which is 5.5*60=330 minutes later).

The speeds have to be converted to km/min as well:

88 km/h = 88/60 km/min
76 km/h = 76/60 km/min

Let's define the location dimension x as x=0 at Town A, then x=976 in Town B.

With this we can set up two location equations:

Andy: x(t) = 88/60 t
Bernard: x(t) = 976 - 76/60 t

When they meet, the equations are equal, so we solve t for:

88/60 t = 976 - 76/60 t => t=510

Convert this number back to a clock time by adding 510 minutes to 9 AM, and you get 5:30 PM.
