Question

Answer in correct significant figures.

2) A 10-g of a chocolate called SWEET contains 9.0 kilocalories (kcal). To compensate for the SWEET he eats, Song Kang jogs for 4 hours around the Hans River Path in South Korea at a speed of 19.3 km/hr. With this speed, Song Kang is able to burn 12,893 calories (cal) per day. Supposed that Song Kang eats one 10-g SWEET every Mondays to Wednesdays, one 15-g SWEET every Thursdays and Fridays, and one 10-g SWEET every Saturdays and Sundays. During Mondays to Wednesdays, Song Kang can jog for 4 hours each day with a speed of 19.3 km/hr. Song Kang skips his jogging sessions on Thursdays and Fridays. On Saturdays and Sundays, Song Kang jogs again for 4 hours but only at a speed of 4.6 m/s. With this information, is Song Kang able to burn the calories he has consumed from SWEET in a week? If no, how much calories do Song Kang still need to burn? Assume that there is a direct relationship between the amount of calories burned and jogging speed. Use ratio and proportion to determine the amount of calories in a 15-g SWEET and to compute the calories burnt by jogging 4 hours at a speed of 4.6 m/s.
