Time t=270 minutes=270/60=9/2 hours
distance s=63 miles
average speed v=s/t=63 ÷

=63×

=14 miles/hour

- In a solution, the solutes particles are distributed uniformly in the solvent.
- The solute is the substance that is dissolved to make the solution.
- Solutes are usually present in a small amount than the solvent.
- The solvent acts as the dispersing medium which allows the solute to go into the solution.
- The solute can be solid, liquid or gas.
