Convert units using the conversion ratio 1 mile = 1.6 km to find the solutions to the mathematical problems.

🙂 = Correct, ☹️ = Incorrect

📌 Rules

• Converting miles to kilometres (Multiply by 1.6 or 8/5): Since 1 mile equals 1.6 km (or 5 miles = 8 km), multiply the number of miles by 1.6. For example, to convert 10 miles to kilometres, multiply 10 × 1.6 = 16 km (or 10 ÷ 5 = 2, then 2 × 8 = 16 km).

• Converting kilometres to miles (Divide by 1.6 or multiply by 5/8): To change kilometres back into miles, divide by 1.6 (or divide by 8 then multiply by 5). For example, to convert 40 km into miles, divide 40 ÷ 8 = 5, then multiply 5 × 5 = 25 miles.

💡 Tips

• Use the 5 miles = 8 km relationship: Thinking in terms of 5 miles being roughly equal to 8 km makes mental conversions simple without needing long multiplication or division.

• Quick typing on our platform: Typing your answer is designed to be super quick and simple! Just type plain digits or decimals like 16 or 25 without adding any commas or spaces.

⚠️ Warnings

• Do not mix up multiplying and dividing: Miles are longer than kilometres, so the number of kilometres will always be larger than the number of miles for the same distance. Doing 10 ÷ 1.6 = 6.25 km for 10 miles is incorrect!

• Watch out for decimal place values: When multiplying by 1.6, make sure to place your decimal point carefully. For example, 15 miles × 1.6 = 24 km, not 240 km.
