A sea lion swims in still water at the speed of 15 km/h. While hunting for fish it swims with the current for 35 km and against the same current for 25 km. The sea lion swims with the current for the same time it swims away from the current. What is the speed of the current?

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
