# Good swimmer

Good swimmer swims 23 m distance with ten shots. With how many shots he swim to an island located 81 m if still swims at the same speed?

Result

n =  36

#### Solution:

$z=23/10=\dfrac{ 23 }{ 10 }=2.3 \ \text{m} \ \\ s=81 \ \text{m} \ \\ n=\lceil s/z \rceil=\lceil 81/2.3 \rceil=36$
