Answer:

Two collinear rays are parallel to each other.

Step-by-step explanation:

Two collinear rays parallel to each other, and they are on the same plane. Thus they do not meet even when extended till infinity.

An example of collinear rays is when you draw two parallel rays on a plain paper placed on an horizontal surface.

A car drives 494 km in 4 hours 45 minutes what is its average speed in kilometers per hour?
Artist 52 [7]

The average speed is 104 kilometer per hour

<em><u>Solution:</u></em>

Given that,

A car drives 494 km in 4 hours 45 minutes

To find: Average speed in kilometers per hour

<em><u>The average speed is given by formula:</u></em>

Average\ speed = \frac{distance}{time}

From given,

Distance = 494 km

Time = 4 hours 45 minutes

We know that,

1 hour = 60 minutes

Therefore,

45\ minutes = \frac{45}{60}\ hour\\\\45\ minutes = 0.75\ hour

Thus,

time = 4 hours 45 minutes = 4 hour + 0.75 hour = 4.75 hour

<em><u>Thus average speed is:</u></em>

Average\ speed = \frac{494}{4.75}\\\\Average\ speed = 104

Thus average speed is 104 kilometer per hour

Two planes travel at a constant speed. Plane A travels 2,800 miles in 5 hours. Plane B travels 3,885 miles in 7 hours.
kozerog [31]

Answer: First.

Step-by-step explanation:

Let's find the speed of the first airplane:

2800 ÷ 5 = 560 (miles per hour)

Let's find the speed of the second plane:

3885 ÷ 7 = 555 (miles per hour)

Thus, the first plane flies faster than the second.

Find the first five terms of the sequence.<br><br> a(n)= 3/5
kvasek [131]

               <em>a(n) = 3/5</em>

I'm sorry if this is not what you're expecting.  But that equation says that
the value of the term doesn't depend on where it is in the sequence ...
on 'n' .

Every term is the same number.  No matter what 'n' may be, the value of 
a(n)  is always 3/5. 

The first five, fifty, five hundred, or five thousand terms are all  3/5 .
