The Kentucky Derby distance is 20 furlongs. How far is the Kentucky Derby in rods and fathoms?

Leona [35]

Answer:

The distance is equivalent to 800 rods and 2200 fathoms.

Step-by-step explanation:

Given:

The distance of the Kentucky Derby in furlongs is 20 furlongs.

Now, in order to convert the distance in rods and fathoms, we use the conversion factor for each.

We know that,

1 furlong = 40 rods.

Therefore, the conversion factor is $\frac{40\ rods}{1\ furlong}$

So, 20 furlongs is equivalent to rods = $20\ furlongs\times \frac{40\ rods}{1\ furlong}=800\ rods$

Therefore, 20 furlongs is equivalent to 800 rods.

Now, we also know that,

1 furlong = 110 fathoms

So, the conversion factor is $\frac{110\ fathoms}{1\ furlong}$

So, 20 furlongs is equivalent to rods = $20\ furlongs\times \frac{110\ fathoms}{1\ furlong}=2200\ fathoms$

Therefore, 20 furlongs is equivalent to 2200 fathoms.

Kia thinks that every number has at least two factors. Which explains whether Kia is correct?

elena-14-01-66 [18.8K]

Solution:

Yes , what mathematics say that every real number has at least two factors apart from number 1 and -1.

The number zero has infinite factors.

The number 1 and -1 which is neither prime nor composite has only 1 factor i.e itself.

Prime integers has only two factors one and itself.

Non prime integers has more than two factors.

But when you say a number apart from natural, whole and integers it includes rational ,and irrational and when we combine them The set is called Real number. .So, Yes this statement is true for rational and irrational also.

So, yes Kia is not absolutely true, but if she has written the statement in this form: Apart from 1 and -1 , every number has at least two factors then it would have been a true statement.
