According to the given data we have the following:
A diver ascended 9/10 of a meter in 1/10 of a minute, hence a full minute=10/10 becuase 9/10*1/10=10/10
Therefore, in order to calculate the diver's rate of ascent we would make the following calculation:
diver's rate of ascent=9/10*10
diver's rate of ascent=9
Therefore, the rate would be 9 meters per minute
