Divide 297 into three parts which are in the ratio 5 : 13 :15​

45:117:135

Step-by-step explanation:

We can solve this by turning each part into a fraction of the whole and multiply this by 297. To do this we first add the numbers in the ratio together to find out how many total divisions we have. 5+13+15 = 33

Let's start with 5. The amount in the 5 part of the ratio will be 5/33 so we can just multiply this fraction by 297 and it will give us the number.

5/33 x 297 = 45

We can then repeat this process with the other two parts:

13/33 x 297 = 117

15/33 x 297 = 135

Therefore our three parts are:

45:117:135

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
