How long would it take to travel 185 miles at 56mph?

Answer 1

You need to ask yourself "how many times does 56 go into 185?" i.e 185/56, which is approximately 3.036 times. (This means 3 hours and 0.036 of an hour)

Now, you need to find what "0.036" of an hour is, so multiply 60 (minutes) by 0.036, which equals 2.16 (2 minutes and .16 of a minute). Thus far your answer is 3 hours, 2 minutes and 0.16 of a minute, (which we have not yet worked out in seconds).

To find 0.16 of a minute, do 60 (seconds) times 0.16, which equals 9.6 seconds. (Round up to 10 seconds).

Answer = 3 hours, 2 minutes, 10 seconds.

The reason you have to keep finding out what 0.036 of an hour/0.16 of a minute is by multiplying is that hours and minutes are not metric (which would make the sums much easier if they were). If there were metric, 0.16 of an hour would be 16 minutes.
