A tortoise is walking in the desert. It walks at a speed of 8 meters per minute for 87.5 meters. For how many minutes does it walk?

OpenStudy (vuriffy):

For this, you just do 87.5/8.

OpenStudy (vuriffy):

Distance divided by time. #physics.

OpenStudy (vuriffy):

Not sure, if you round to a certain decimal, or if you keep the decimal exact as it is for this, since the question did not state it.

OpenStudy (lyssburleson):

i'd assume i would have to round it

OpenStudy (vuriffy):

If you did, you would do 11 for whole number, 10.9 for tenths, 10.94 for hundredths, 10.938 for thousandth, and 10.9375 for exact.

OpenStudy (vuriffy):

Do you understand why they round the way they do?

OpenStudy (lyssburleson):

yes

OpenStudy (vuriffy):

But, yes, if it is surely whole number, I would agree it to be 11.

OpenStudy (lyssburleson):

Okay, thats what i was going to put

OpenStudy (vuriffy):

Great job!
