Question

11. A town that uses 68 million BTUs of energy each month is using how many kilowatt-hours of

energy? (1 kWh-3400 BTUS)

Answer 1

`20,000 \text{ kWh}`

Explanation:

We can convert 68 million British Thermal Units (BTUs) to kilowatt-hours (kWh) using the given conversion ratio:

`\frac{1 \text{ kWh}}{3400 \text{ BTUs}}`

Multiplying by the ratio:

`68,000,000 \text{ BTUs} \cdot \frac{1 \text{ kWh}}{3,400 \text{ BTUs}}`

↓ canceling the BTU units

`68,000,000\cdot \frac{1 \text{ kWh}}{3,400}`

↓ executing multiplication

`(68,000,000)/(3,400) \text{ kWh}`

↓ rewriting as a decimal

`\boxed{20,000 \text{ kWh}}`
