Question

Ali swam 0.5 squared kilometers in January and 0.3 cubed kilometers in February. What is the total distance he swam for both months? 1.9 kilometers 0.277 kilometers 0.727 kilometers 0.8 kilometers

Answer 1

d = 0.277 km

Explanation:

Distance covered in January = 0.5² km

The distance covered in February = 0.3³ km

We need to find the total distance he swam for both months. It can be calculated by finding their sum. So,

`d=0.5^2+0.3^3\\\\d=0.25+0.027\\\\d=0.277\ km`

So, he swam 0.277 km for both months. Hence, the correct option is (b).
