In horse racing, 1 furlong is 220 yards. How many feet are in 15 furlongs?

Hint: In this problem, we have to find how many feet are in 15 furlongs. We are given that 1 furlong is 220 yards. We can first find the measurement in yards by multiplying the given yards to the given 15 furlongs. We can use the conversion formula 1 yard = 3 feet, we can now multiply the resulting yard in the conversion formula to get the final measurement in feet.

Complete step-by-step solution:
We know that we are given,
1 furlong = 220 yards.
We have to find how many feet are there in 15 furlongs.
We can now multiply the 15 furlongs to the 220 yards to find the resulting measurement in yards.
We know that 15 furlongs will be,
\[\Rightarrow 15\times 220=3300\] yards. …… (1)
We also know by measurement conversion,
1 yard = 3 feet.
We can now find the m=feet measurement by multiplying (1) and 3, we get
\[\Rightarrow 3\times 3300=9900\]feet.
Therefore, 9900 feet are there in 15 furlongs.

Note: Students make mistakes while using the conversion formulas, we should remember some conversion formulas like 1 yard = 3 feet. We should also know that if 1 furlong = 220 yards the 15 furlongs will be the multiplication of 15 and 220. We should also remember that unti symbol should be written when writing the final answer.
