When a solution is heated, the solvent evaporates, leaving behind the dissolved solids as residue. When a solution containing dissolved solutes is heated, the solvent will evaporate. Only the solute will remain in the evaporating dish.

speed of the two vehicle are 55 mph and 35 mph
Explanation:
given,
speed of friends vehicle = x mph
speed of your vehicle = (x - 20) mph
when both travel in opposite direction
distance between the two buses = 270 miles
distance = speed × time
270 = 3(x) + 3(x-20)
90 = 2 x -20
x = 55 mph
now, speed of other vehicle is (55-20) = 35 mph
hence, speed of the two vehicle are 55 mph and 35 mph
