Earth has 24 time zones spread over its 360º circumference. Each time zone is 15º wide. Boston is close to longitude 71º W; Honolulu is close to longitude 158º W.
How many time zones apart are Boston and Honolulu?
A. They are 6 time zones apart because 87/15 ≈ 6.
B. They are 5 time zones apart because 360/71 ≈ 5.
C. They are 4 time zones apart because 87/24 ≈ 4.
D. They are 2 time zones apart because 158/71 ≈ 2.
I think it's either B or D, but i'm not certain.
A grizzly bear’s top speed is about 36 mph. This speed makes the bear about 1 times as fast as an African elephant.
What is the top speed of an African elephant?
A. An African elephant can reach a top speed of about 48 mph because 36 divided by 2/3 = 48.
B. An African elephant can reach a top speed of about 39 mph because 36 divided by 3/2 = 39 .
C. An African elephant can reach a top speed of about 34 mph because 36 divided by 2/3 = 34 .
D. An African elephant can reach a top speed of about 24 mph because 36 divided by 3/2 =24 .
Question 1. Answer: A We know that each time zone is 15 degrees. We know that Honolulu is close to 158 degrees and Boston is close to 71 degrees
If we subtract 158 - 71= 87 degrees Since we know that time zones are 15 degrees wide we divide 87/15 = 5.8 or roughly 6 as the answer states
Question 2. I am guessing the question is written incorrectly as 1 times as fast as the bear would be the same speed. However, by looking at the answers I am guessing it was supposed to be 1.5 times as fast and the answer is D
