Question

The motion of the earth's crustal plates is described by a model referred to as a tectonic .measurement indicate that the Borneo island have westward plate tectonic speed of 1.3 cm per year.estimate the time it would take for this motion to carry Borneo to Singapore island.(assume a distance of 750km)

Answer 1

Divide 750 km by 1.3 cm/year (i.e. divide travel distance by speed) to get time.  You should first do some unit conversions, like converting km to cm or cm to km, and get your answer in years.
