math question on homework???

i really dont understand how to do this, help me please!

If Columbus and his three ships sailed their infamous trip today, how much further would they have had to travel to reach the West Indies than they actually traveled in 1492? Assume seafloor spreading has continued at the rate 5 cm / year over this period.

I used

Distance = Speed times Time

i tried using 515 years as the time, but my teacher said look it over again and i had gotten it wrong. help me please!!!

It would seem that you would multiply 515 years and 5 cm/year which would give 2,575 cm per ship.

the change in years is 515 like you got

at 5cm/year for 515 years is 5150/2=2575cm

unless it’s a trick question, 4 ships means 10300cm between them

well techincally columbus didnt sail in a striaght line either which is what the previous one assumed. the indies are a good bit south of rngland so he had to sail more of a diagional. the previous equation tells you how much further spread they were but perhaps you should try figuring out what the new diagional would. since the hieght of the trigianal didnt change just the width, just a thought

brudder…
hmm… tough one..

Seafloor spread does not constitute continental drift… and the oceans are deep.

I would therefore discount the spreading rate over the 515 years.. and just assume that it would take the same distance.

Anyway…. what’s 25.75 meters for a ship… it’s just a shove away…

I don’t see what your teacher could mean here, did you multiply correctly? 515 x 5=2575 cms.
