mondeo timing belt change interval

Hello, I have a mondi 16 V 1.8 bj 1995 and with a running capacity of 116000 km, the timing belt has already been changed at 60,000 km from the previous owner. I would like to know if the timing belt has to be changed again now? what if it would tear, can one then install new ones and it will run again? and how expensive is the change for a workshop?? and what can this cost to a general workshop around the corner?? I would be very grateful if some of you would give me this Thank you in advance!
