Question

Anand and Amir ran $35km750m$ and $28km90m$, respectively in two hours. Who ran more and by how many kilometres.

Answer 1

Step 1- Converting them in one unit

$$\begin{gathered} 35km750m=35km+750m \\ 35km750m=35km+\frac{750}{1000}km \\ 35km750m=35km+0.750km \\ 35km750m=35.750km \end{gathered}$$

$$\begin{gathered} 28km90m=28km+90m \\ 28km90m=28km+\frac{90}{1000}km \\ 28km90m=28km+0.090km \\ 28km90m=28.090km \end{gathered}$$

On comparing, $35.750>28.090$

Therefore, Anand travel more distance.

Step 2 - Now, Subtracting both

$35.750+28.0907.660$

Therefore, Anand travels $7.660km$ more than Amir.
