3 \text{ hours } \longrightarrow 31 \text{ cogs}

Find 1 hour:

1 \text{ hours } \longrightarrow 31 / 3 \text{ cogs}


1 \text{ hours } \longrightarrow (31)/(3) \text{ cogs}

Find 40 hours:

40 \text{ hours } \longrightarrow (31)/(3) * 40 \text{ cogs}


40 \text{ hours } \longrightarrow ((40)31)/(3) \text{ cogs}

Answer: Option 4
