To calculate how many calories Jasmine burned while shoveling snow for 1½ hours:

  1. Convert 1½ hours to minutes: \[ 1 \text{ hour} = 60 \text{ minutes} \ 1½ \text{ hours} = 90 \text{ minutes} \]

  2. Determine how many 10-minute intervals are in 90 minutes: \[ 90 \text{ minutes} \div 10 \text{ minutes/interval} = 9 \text{ intervals} \]

  3. Calculate the total calories burned: \[ 9 \text{ intervals} \times 65 \text{ calories/interval} = 585 \text{ calories} \]

Thus, the number of calories Jasmine burned is 585 calories. The correct answer is d) 585.
