The scale factor is 7.5 because if you divide 30 by 4 and 45 by 6, it is 7.5.
So to find the actual measurement of Harper's bedroom, you multiply 1.2 by 7.5, that would be 9 feet wide, and 1.6 by 7.5, that would be 12 feet long.
9 feet wide, 12 feet long

The arithmetic sequence is 40, 47, 54 etc. In this case, the arithmetic difference is 7 and a1 being the first term is 40. Hence the arithmetic equation is an = 40 + 7*(n-1) where an is the nth term and n is an integer. Hence the answer to this problem is B.<span>a_n = 40 + 7(n − 1) where n ≥ 1 </span>
To find kilometers per hour, we need to multiply 2 1/6 by 3, because it took Linley 1/3 hour to ride that far.
2 1/6 * 3 = 6 1/2
So, her average speed in kilometers per hour is 6 1/2 kph
