Question

Pls help me answer the questions in the picture below the picture below has the question and table to fill out

Answer 1

Recall that to be able to add two quantities, they must have the same units.

We know that:

$1\operatorname{km}=1000m\text{.}$

Therefore:

1)

$\begin{gathered} 15000\operatorname{km}+41000m=15000\times1000m+41000m \\ =15000000m+41000m=15041000m\text{.} \end{gathered}$

2) We cannot convert from kilograms to meters, therefore we cannot add them.

3)

$22m+27m=49m\text{.}$

Answer:

1) 15000 km+4100m=15041000m,

2) No.

3)22m+27m=49m.
