Given the statement:
Olivia is 4 feet 10 inches tall. She compared her height with her younger sister, Susan, and found that Susan is 15 inches shorter than she is.
Determine Olivia's height in inches, and Susan's height in centimeters.
Solution:
Convert first 4 feet to inches then add 10 in order to determine Olivia's height.
1 ft = 12 inches
4 ft = 48 inches
= 48 + 10
Olivia's height = 58 inches
Susan's height =58 inches - 15 inches
= 43 inches
Convert 43 inches to cm by using the general conversion method.
= (43 inches)(2.54 cm/ 1 inch)
= 109.22 cm
Susan's height = 109.22 cm
Final answer:
Olivia's height = 58 inches
Susan's height = 109.22 cm
