Speed, distance, time help?

Question

if the distance is 180 and the speed is the mph would the answer be 3.27 but how do you change that into decimal time

Answer 1

180 miles? If the answer is 3.27 hours you're talking a little bit more than a quarter of an hour over 3 hours, so .27 x 60 minutes = 3 hours and 16.2 minutes (3h16m20s).

Answer 2

You haven't listed the speed, but it looks like it was 55 mph.

180 miles / 55 mph = 3.27272727 hours

Now you want that in hours and minutes (and seconds perhaps?)

3.2727 = 3 hours + 0.2727 of an hour.

Take the 0.2727 and multiply it by 60 minutes:

0.2727 x 60 = 16.362 minutes

That's 16 minutes + 0.362 of a minute.

Take the 0.362 and multiply it by 60 seconds:

0.362 x 60 = 21.72 seconds

Here you can round up if you like.

Answer:

3 hours, 16 minutes, 22 seconds (approximately)
