Question

If Alex walks 52 steps in a minute, then find the number of steps walked by him in 20 minutes.

• A. 1040

Answer 1

The correct option is A 1040
Number of steps Alex walks in 1 minute = 52
Number of steps walked by him in 20 minutes = 52 × 20
$\begin{array}{ccc}& 50& 2\\ 20& 20\times 50& 20\times 2\\ & =1000& =40\end{array}$
52 x 20 = 1000 + 40 = 1040
Hence, Alex walked 1040 steps in 20 minutes.
