Say if the Earth rotates 1.25 degrees in 5 mintues. But a classmate wants to find out how many degrees the Earth can rotate in 2

minutes. She does a problem:  she  puts 1.25 over 5  and divides them both  by 2, and her answer was 0.625 over 2.5.  Explain her error and give the correct rate.
(Please help Thanks!)

Her error was dividing them by 2 she would place 1.25 over 5 then divide by 5 to get the unit rate per minute then multiply the quotient by 2 to get the rate of degrees moved for 2 minutes which is .5  or .50 degrees every two minutes.

According do what i came up with. after 3 hours train (A) should be 150 miles out towards Smithville, while Train (B) will be 180 miles out towards Westtown. Its best to graph this out to better understand. so 330/2 = 165, so thats your half way point. use this to determine how far train (A) is from SV compared to train (B)s distance to WT. After 3 hours you can see at 180 miles out Train (B) will be crossing paths with Train (A) at 150 miles. So the answer would be 3 hours

Pamela is incorrect. When you multiply anything negative by a negative, the product will always be a positive. Because the two negative signs cancel each other out.
