Complete a chair conformation of trans-1-bromo-3-methylcyclohexane by placing the hydrogen, bromine, and methyl groups in the appropriate positions. Place the bromine on the carbon that is more to the right.

Explanation:

The most highly stable cycloalkane is cyclohexane. It does not suffer from an angle or torsional strain, and it has the appropriate stability as chain alkanes. Because of the peculiar conformation it takes, this stability leads to the cyclohexane conformation popularly known as the "chair" conformation.

However, from the information given;

The chair conformation structure of  trans-1-bromo-3-methylcyclohexane is carefully drawn and the substituents are appropriately attached in the image below.

"record the time to complete a chemical reaction" would most likely be part of a lab procedure.
