So we have 65/1 (65mph), and 260/x, x being the amount of hours we need.
Cross multiply 260 by 1, and 65 by x. Once we do that, divide 260 by 65x.
260/65x.
Divide both sides by 65.
4=x.
It will take him 4 hours. Hope this helps!

Step-by-step explanation:
The answer is above
Answer: √10, √27, and √99 are all the irrational numbers from the list.
√10 = √(5*2) = √5 * √2 ----> irrational
√27 = √(9*3) = (√9) * √(3) = 3√3 ----> irrational
√99 = √(9*11) = (√9) * (√11) = 3√11 -------> irrational
√(49) = 7 -----> rational
√(64) = 8 ----------> rational
