The Ostrich will take 64 minutes to cover 40 miles.
Data;
- rate = 25 miles in 40 minute
<h3>Rate</h3>
To calculate the time it will take the ostrich to cover 40 miles, we have to compare it with the rate (speed).
![25mi = 40 min\\40 mi = x min](https://tex.z-dn.net/?f=25mi%20%3D%2040%20min%5C%5C40%20mi%20%3D%20x%20min)
Cross multiply both sides
![x * 25 =40 * 40](https://tex.z-dn.net/?f=x%20%2A%2025%20%3D40%20%2A%2040)
simplify the value
![x*25=40*40\\25x = 1600\\](https://tex.z-dn.net/?f=x%2A25%3D40%2A40%5C%5C25x%20%3D%201600%5C%5C)
divide both sides by the coefficient of x
![25x = 1600\\25x/25 = 1600/25\\x = 64](https://tex.z-dn.net/?f=25x%20%3D%201600%5C%5C25x%2F25%20%3D%201600%2F25%5C%5Cx%20%3D%2064)
From the calculations above, it would take the ostrich 64 minutes to cover 40 miles.

Answer:
1/13
Step-by-step explanation:
There are 4 king cards:
King of Hearts
King of Diamonds
King of Clover
King of Spades
This is 4 cards in a standard deck of 52. Set as a fraction 4/52.
Simplify:
(4/52)/(4/4) = 1/13
1/13 is the probability of drawing a KIng card.
