A penguin walks 10 feet in 6 seconds. At this speed: How far does the penguin walk in 45 seconds?
How long does it take the penguin to walk 45 feet?
Use may use the table to find the answers to both questions.

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)

These are the multiples of 15 but what you are probably asking or what are the factors of 15
