Question

For every 6 inches of height, Lashacha has an arm span of about 6.17 inches. If Lashacha is 6 ft 5 in. tall, predict the width of her arm span.

Answer 1

Answer: 79.18 inch.

Explanation:

Given: For every 6 inches of height, Lashacha has an arm span of about 6.17 inches.

i.e. for each inch of height she has an arm span of =
`(6.17)/(6)` inches

Height of Lashacha = 6 ft 5 in.

1 ft = 12 inches

Then, Height of Lashacha = [6(12)+ 5] = 77 in.

So for 77 inch height she has arm span of
`(6.17)/(6)*77=79.18\text{ inch}`

Hence, the width of her arm span = 79.18 inch.
