The number line showing the location of the two numbers is attached below. Therefore:
Answer:
2.5 miles
Step-by-step explanation:
The relation between time, speed, and distance is ...
distance = speed × time
We can define t to be Stanley's swimming time. Then t+0.5 was his running time, and 2(t+0.5) was his biking time. His total distance covered is ...
64 = 9(t +0.5) +16(2(t +0.5)) +2.5(t)
64 = 43.5t +20.5 . . . . . . . simplify
43.5 = 43.5t . . . . . . . . . subtract 20.5
t = 1 . . . . . . . . . . . . . . divide by the coefficient of t
Stanley swam for 1 hour, so the distance he covered while swimming was ...
(2.5 mi/h)(1 h) = 2.5 mi
Stanley covered 2.5 miles while swimming.
_____
<em>Additional comment</em>
Stanley ran for 1.5 hours, covering 9×1.5 = 13.5 miles. He biked for 3 hours, covering 16×3 = 48 miles. His total distance was 2.5 +13.5 +48 = 64 miles, as given.

Answer:
(D) 2√3
Step-by-step explanation:
From the above question ,we are asked to solve for:
6/√12 −√3
In other to simplify, we would expand the numerator of 6/√12
So we have;
= [6/(√4 ×√3)] - √3
= (6/ 2 ×√3) - √3
= (6/2 × √3) - √3
= (3 ×√3) - √3
= 3√3 - √3
= 2√3
Therefore, the value of 6/√12 −√3 is
option (D) 2√3
