Two automobiles are 150 kilometers apart and traveling toward each other. One automobile is moving at 60km/h and the other is moving at 40km/h mph. In how many hours will they meet?
A. 2.5
B. 2.0
C. 1.75
D. 1.5
E. 1.25
D. 1.5
One moves at 60km/h, so in an hour, he’ll travel 60km
The other moves at 40km/h, so in an hour, he’ll travel 40km
This is towards each other, so, in an hour, we can say that they’ll get 60+40=100km closer.
This means that they get closer at 100km/h
Given that we have the distance of 150km, and the speed of closure at 100kmh, we can now use the equation
S=D/T
Rearrange to find T (times both sides by T)
S x T = D (now divide both sides by S)
T=D/S
Time = 150km divided by 100km/h
Time = 1.5 hours
Or one hour and 30 minutes

Sodium carbonate is produced by____________?
A. haber process
B. Amonia solvay process
C. decons process
D. lead chamber process
B. Amonia solvay process
Sodium carbonate (also known as soda ash) is produced by the Ammonia solvay process. The Ammonia solvay process is an industrial process used to produce sodium carbonate from salt (sodium chloride) and limestone. It involves the reaction of sodium chloride with calcium carbonate (from limestone) in a solution of ammonia to produce sodium carbonate and calcium chloride. The sodium carbonate is then recovered from the solution by crystallization.
A. The Haber process is used to produce ammonia.
C. The Decons process is not a well-known industrial process.
D. The Lead chamber process is used in the manufacture of sulfuric acid.
