Mathematics
1 answer:
Vitek1552 [10]3 years ago
4 0

Answer:

n = 3

Step-by-step explanation:

Let's consider the following proportion.

2/n = 2/3

To solve a proportion, we can use the rule that states that <em>the product of the end-terms is equal to the products of the inner-terms</em>. That is,

end-term × end-term = inner-term × inner-term

2 × 3 = 2 × n

6 = 2 × n

We can solve for n, dividing both terms by 2.

6/2 = 2 × n/2

n = 3

Mara's family is driving to her grandmothers' house. The family travels 239.4 miles between the hours of 9:10 a.M. To 1:40 p.M.
anzhelika [568]

Answer:

53.2 mph

Step-by-step explanation:

Mara's family travels 239.4 miles between the hours of 9:10 a.m. to 1:40 p.m.

1:40 p.m. is 13:40.

Thus, they traveled for

13 hours 40 minutes - 9 hours 10 minutes = 4 hours 30 minutes

that is 4\frac{1}{2}=4.5 hours.

Use formula:

D=r\cdot t,

where

D = distance

r = rate

t = time.

In your case,

D = 239.4 miles

t = 4.5 hours

Hence,

239.4=4.5r\\ \\r=\dfrac{239.4}{4.5}=53.2\ mph
