//1-using the console calculate the average age of the follwing ages [13,14,13,15,16,17,19,13,16,15].
var avg=0
for(i=13;i<=15;i++){
	avg+=i

// 2-using the console calculate your age in seconds.

var myAge=21*365*24*60*60
// 3- Write a function identity that takes one parameter and returns that input value.
// Calling your function should result in:
// identity("hello world");  ==> "hello world"
// identity(500);  ==> 500
function identity(par){
	return par
}

// 4- Write a function convertTo that takes  a string and a number as parameters.
// If the string input is "cm", then the function should convert the 2nd argument into centimeters by multiplying it to 2.54 and returning that value.
// If the string input is "in", then the function should convert the 2nd argument into inches by dividing it by 2.54.
// Calling your function should result in something like:
// convertTo('cm', 100);  ==> 254
// convertTo('in', 50.8); ==> 20

function convertTo(units, num) {
  // write your code here
	if (units==='cm'){
		return num*2.54
	}
	return num/2.54
}

//4- Write a function dogsIWouldPet that takes an item (string), 
//and returns a sentence stating dogs you would pet in comparison to the item (see sample call below).
// Calling your function should result in:
// dogsIWouldPet("ottoman"); //"I would pet dogs no bigger than an ottoman"
// dogsIWouldPet("small horse"); //"I would pet dogs no bigger than an small horse"
// dogsIWouldPet("Terrier"); //"I would pet dogs no bigger than an Terrier"
// Bonus (extra): If your function were passed in a string "I do not like dogs", 
//you can have your function return "I would not pet dogs".


function dogsIWouldPet (str){
	if(str==="ottoman"){
		return "I would pet dogs no bigger than an ottoman"
	}
	if(str==="small horse"){
		return "I would pet dogs no bigger than an small horse"
	}
	if(str==="Terrier"){
		return "I would pet dogs no bigger than an Terrier"
	}
	if(str==="I do not like dogs"){
		return"I would not pet dogs"
	}
}

// 5- Write a function convertToKilometers that takes a number of miles passed in as parameter, 
// and returns that number multiplied by 1.60934 (an accepted approximation of 1 mile in kilometers).
// Calling your function should result in:
// convertToKilometers(50);   ==> 80.467
// convertToKilometers(361);  ==> 580.973
function convertToKilometers(num){
	return num*1.60934
}
