Light travels about 180 million kilometers in 10 minutes. How far does it travel in 1 minute ? How far does it travel in 1 secon

daser333 [38]

Answer:18 million and 300000

Step-by-step explanation:

Since light travels 180 million KM in 10 min, it would travel 180 million/10 in one minute. Thus, we get 18 million. As we know, there are 60 seconds in a min. Thus, there are 60*10=600 seconds in 10 minutes. Thus, 180 million/600 gives 300000

Four friends buy cinema tickets using this offer. Cinema tickets buy 3 tickets and get a ticket free they each pay £6.15 how muc

laila [671]

The cost of one ticket will be £8.20

<em><u>Explanation</u></em>

Suppose, the cost of one ticket is $x$

As the offer says "buy 3 tickets and get a ticket free" , it means <u>they actually need to pay for 3 tickets</u>.

So, the total cost of 3 tickets $=3x$

Each of four friends pay £6.15 , so the <u>total amount they pay</u> $=\£6.15 *4 = \£24.60$

Thus, the equation will be .....

$3x=24.60\\ \\ x=\frac{24.60}{3}=8.20$

So, the cost of one ticket will be £8.20

Nikitich [7]

Answer:

The original price of the sweater was $28

Step-by-step explanation:

To find out the answer to this problem you need to first convert the percent into a decimal which would be 0.4 and then to solve the problem in one step you need it to be 140% which would be 1.4 as a decimal. Then you need to multiply 20 by 1.4 which gives you 28 and 28 would be the total cost of the shirt at it's regular price.
