This math problem has got me stumped: Running for 2 hours, Jonah burnt 30 calories every hour. How many more calories would he have lost if he would have run for five hours?
Can you show me the way?
When Jonah ran for 2 hours, burning 30 calories every hour, he burnt a total of 2*30=60 calories.
If he had run for five hours, losing 30 calories every hour, Jonah would have burnt 5*30=150 calories.
The difference in the number of calories Jonah would have burnt if he ran for five hours instead of 2 hours is 150-60=90 calories.
