That car moves or accelerates faster which has the higher speed.
If the red car accelerate at higher speed than black car then the red car reach first on the destination but if the black car moves with higher speed than red car then the black car reach its destination earlier than the red car.
The conclusion can be drawn when the image is present or any data but there is no data or image present which provides us accurate information so we can conclude logically that car which moves at higher speed will move faster than the other car.

The relation between molecular (formula) mass and molar mass Page 4 4 • To obtain one mole of copper atoms (6.02 x 1023 atoms), weigh out 63.55 g copper. The molar mass (M) of a substance is the mass of one mole of entities (atoms, molecules, or formula units) of the substance.
The number of moles of reactants and products can be used to obtain the mass of products formed. The results obtained are as follows;
- The mass of hydrogen produced is 0.0174 grams
- The mass of zinc produced is 0.5688 grams
- The percentage by mass of zinc in the brass alloy is 47.3 %
The question says that HCl was in excess. It means that after the reaction, we will have unreacted HCl(aq) and ZnCl2(aq) in the remaining solution.
Hence;
Mass of ZnCl2(aq) formed = 36.309g - 35.123g = 1.186g
Number of moles ZnCl2(aq) formed = 
= 0.0087 moles
From the reaction equation;

To obtain the amount of Zn reacted
1 mole of Zn yields 1 mole of ZnCl2
x moles of Zn yields 0.0087 moles of ZnCl2
x = 0.0087 moles of Zn
a) 1 mole of Zn yields 1 mole of H2
0.0087 moles of Zn yields 0.0087 moles of H2
Mass of H2 = 0.0087 moles of H2 * 2 g/mol = 0.0174 grams
b)
Mass of Zn reacted = 0.0087 moles of Zn * 65.38 grams/mole = 0.5688 grams
c)
Percentage of Zn in the alloy = 0.5688 grams/1.203g * 100 = 47.3 %
