Assume the marked speed
limit is 65 miles per hour on a highway in which you are traveling 232 miles. If you go
the speed limit, how many kilometers per second are you traveling?

Thank you for the opportunity to help you with your question!

If
we want to know how to work out how many kilometers per second we are
travelling, first we must convert the miles to kilometers. To do this,
we multiply the speed in miles(65), by 1.609344.

so 65 X 1.609344 = 104.60736.

now we have kilometers per hour, but we need kilometers per second. So,
if we divide 104.60736 by 60, we will get the kilometers per
minute(because there is 60 minutes in an hour). Then we must divide this
answer again by 60(because there is 60 seconds in a minute) to get the
kilometers per second.

So: 104.60736 / 60 = 1.743456

1.743456 / 60 = 0.0290576

So the car is traveling at 0.0290576 kps(kilometers per second)

Please let me know if you need any clarification. I'm always happy to answer your questions.
