OK, we have the data (numbers) just need the technique.
Explanation:
Speed, s = distance, d / time, t
We can use a variety of units (ways to measure these) but so long as we quote the answer giving the units we used, we’re ok.
So
Next to convert it to mph we need to figure out how many hours in a day and then divide the answer we got by that number.
(As the number of time units (hours) is bigger than the number of time units we had (days) the answer will fall.)
1 day = 24 hours
So speed in mph = speed in miles per day / 24
