Question

A machine can paint 24 cabinet doors in 45 minutes at this rate how many cabinet doors can it paint in 1 hour? (45min=3/4 hours)

Answer 1

We are given the rate at which a machine can paint cabinet doors, which is the following:

`\text{Rate}=\frac{24\text{cabinet doors}}{45\min }`

Converting minutes into hours

`\frac{24\text{cabinet doors}}{45\min}*\frac{45\min}{((3)/(4))\text{hours}}=\frac{(24\cdot4)\text{cabinet}}{3\text{hours}}=32\frac{cabinet}{\text{hour}}`

That means that at this rate, in one hour the numbers of cabinets is 32
