Final answer:
Ken would burn 1080 calories if he were to run for 1 hour and 30 minutes.
Step-by-step explanation:
To find out how many calories Ken would burn if he were to run for 1 hour and 30 minutes, we can use the given information. Ken burns 120 calories in 10 minutes of running.
We can set up a proportion to find out how many calories he would burn in 1 hour and 30 minutes:
10 minutes = 120 calories
1 hour and 30 minutes=90minutes = x calories
We can cross-multiply and solve for x:
10x = 120 *90
10x = 1080
x = 1080
Therefore, Ken would burn 1080 calories if he were to run for 1 hour and 30 minutes.
