The formula used for calculating the time is:
t = d / v
where t is time, d is distance and v is velocity
We know that the difference in the two times is 3 hours, therefore:
d / 65 – d / 130 = 3
Calculating for d:
d = 30 / (1/65 – 1/130)
<span>d = 3900 miles</span>
Answer:
10
Step-by-step explanation:
15 = 1/2 * b * 3
15 * 2 = 3 * b
b = 30/3
b = 10 m
By factoring, x equals both -5 and 7.

Answer:
<em>25 mg. is lighter than 25 cg.</em>
<em />
Step-by-step explanation:
<em>Well,</em>
<em />
<em>The prefix "milli" means thousandth and the prefix "centi" means hundredth. So a milligram will be one-tenth of a centigram.</em>
<em />
<em>10 mg. = 1 cg.</em>
<em>25 mg. = 2.5 cg.</em>
<em />
<em>2.5 cg. < 25 cg.</em>
<em />
<em>25 mg. is lighter than 25 cg.</em>
