In this lesson, you will learn about the mathematicalconcepts involved in international travel. In this activity, you will: *convert temperatures between ºF and ºC *convert currency between countries *convert measurements between the customaryUS units and international metric units. Have a calculator ready! https://www.desmos.com/scientific Practice with Temperature Conversions! Interpret the temperature conversion shown in the gif. 37ºC = ºF -10ºC = ºF Convert -10ºC to F. A formula to convert from Celsius to Fahrenheit is given. ºF = + 32 ºF = ( x 1.8) + 32 A formula to convert from Celsius to Fahrenheit is given. To take 9/5 of a number,you can first take 1/5 of the number, or ÷ 5,and then multiply by 9. ºF = + 32 35ºC = ºF Convert 35ºC to ºF. ºF = ( x 9/5 ) + 32 A formula to convert from Fahrenheit to Celsius is shown. Note: To take 5/9 of a number, you can multiply by 5, and then divide by 9. Convert 50ºF to ºC. ºC = ( ) x 5/9 ºC = ( ºF – 32) x 5/9 50ºF = ºC Converting between international currencies! Convert 525 Greece euros to US dollars.Use an exchange rate of 1 US dollar: 1.14 European euros. Greece USD 1.14x = x = $ US dollars Round to the nearest cent. x = 1.14 1 ← Cross multiply! Convert $500 US dollars to Libyan dinars.Use an exchange rate of 1 US dollar: 1.5 Libyan dinars. US Libya x = Libyan dinars 500 ? x = 1.5 ? 1 ? Refer to the sample problem. 256 km ≈ miles Convert 256 km to miles. 256 km 1 × 1.6 ? 1 ? mi km 4200 miles 1 Convert 4200 miles to km. Use 1 mile = 1.609 km. Round your answer to the nearest km. Please do not use commas in your answer. × 1.609 ? 1 ? mi km ≈ km Convert 60 mph to kph. Use 1 mile = 1.609 km. Please do not round your answer. 60 miles 1 hour × mi km = kpm |
