Speed is calculated using the formula distance divided by time. For a distance of 26.2 miles, and a time of 3 hours and 40 minutes, we first convert the time to make it solely in terms of hours. 40 minutes is 2/3 of an hour, so this is a total time of 3 2/3 or 11/3 hours. If we divide 26.2 miles by 11/3 hours, we get a resulting speed of 7.14 miles/hour.

It's solid at room temperature, It's melting and boiling points are below 30-35°C. It's non-volatile and probably not soluble in water.
I'm sorry but that's all I could come up with since I couldn't quire fathom the question.
Explanation:
A cup of mixtures of iron fillings, sand and salt is a mixture who constituents are in the same phase i.e solid.
To separate them out we use the physical properties of the substances.
- First spread out the mixture uniformly over a piece of paper or on the table.
- Pass a bar magnet over it.
- The iron fillings will become attracted to the magnet and separate from the mixture.
- then pour water into the mixture of sand and salt
- the salt will dissolve since sand is made up of quartz which are highly insoluble.
- separate the water solution. Evaporate to dryness and recover the salt.
- the sand is left behind and dried.
