Answer 1

4 calories

Explanation:

From the table given, the number of calories burnt shows a proportional or linear relationship with the minutes spent while kayaking.

Calories burnt is proportional to the minutes spent.

The calories burnt in 1 minute = number of calories burnt ÷ the number of minutes spent at any given interval.

Since 200 calories are burnt in 50 mins, therefore:

Calories burnt in 1 minute =
`(200 calories)/(50mins) = 4calories/min`
