Bus Timetables - on the instructions of stedge

[Spike On Q]

Bus [guagua] timetables in Fuerteventura only give the starting time of a particular service. It is then left to the customer to calculate the time the bus will arrive at their stop

Is there a calculation I can use say:

No 1 bus leaves Puerto bound for Morro Jable - what time [how many minutes after leaving] will it arrive in Tiscamanita?
