To prepare for a bike race, Rex rides his bike for 13 miles each day for 5 days. The app he uses only tracks distance in kilometers. If 1 mile = 1.61 kilometers, what is Rex's distance in kilometers? Round the answer to the nearest hundredth.
8.07 kilometers
104.65 kilometers
20.93 kilometers
26.19 kilometers
To convert miles to kilometers, you need to multiply the number of miles by 1.61, since 1 mile is equal to 1.61 kilometers.
Rex rides his bike for 13 miles per day for 5 days, so his total distance in miles is 13 * 5 = 65 miles.
To convert this distance to kilometers, you need to multiply by 1.61, so Rex's distance in kilometers is 65 * 1.61 = 104.65.
Rex's distance in kilometers is therefore 104.65 kilometers.
