Solution:
Given expression is
.
Divide the given expression to find the quotient.
Decimal rule when numerator is divided by 10, 100, 1000, 10000 etc..
- If you have one zero in the divisor (10), then the decimal point will move 1 place to the left of the last digit.
- If you have two zeros in the divisor (100), then the decimal point will move 2 place to the left of the last digit.
- If you have three zeros in the divisor (1000), then the decimal point will move 3 place to the left of the last digit.

Here, we have 3 zeros in the denominator.
So, the decimal point is move 3 digit to the left of the last digit.

So, option C is the right answer.
Hence the quotient is 212.96.
Odd question; there's no real rate exact 50 meters per lap (assuming the last is a typo), i.e we have a 50 meter pool.
d = 50 n
so when n=15
d = 50(15) = 750 meters
