Question

Mohit Travels 380 Km Per Day. How much will he travel in 120 days?

Answer 1

Hint: The multiplication of whole numbers may be thought of as a repeated addition; that is, the multiplication of two numbers is equivalent to adding as many copies of one of them, the multiplicand, as the quantity of the other one, the multiplier. Both numbers can be referred to as factors. For example, 4 multiplied by 3, often written as \[3 \times 4\] and spoken as "3 times 4", can be calculated by adding 3 copies of 4 together: \[3 \times 4 = 4 + 4 + 4 = 12\]

Complete step by step answer:
In this question also if Mohit travels 380 KM per day for 120 days continuously is basically
\[380 + 380 + 380 + ................. + 380 = 380 \times 120\]
Which can be also spoken as 120 times 380. So here we will get it as
\[\begin{array}{*{20}{c}}
{}&{380}\\
{}&\begin{array}{l}
 \times 120\\
\_\_\_\_\_
\end{array}\\
{}&{000}\\
{}&{760 \times }\\
{}&\begin{array}{l}
380 \times \times \\
\_\_\_\_\_\_\_
\end{array}\\
{}&\begin{array}{l}
45600\\
\_\_\_\_\_\_
\end{array}\\
{}&{}
\end{array}\]
Which means that Mohit will travel 45600 Kilometers in 120 days.

Note: Multiplication can also be visualized as counting objects arranged in a rectangle (for whole numbers), or as finding the area of a rectangle whose sides have some given lengths. The area of a rectangle does not depend on which side is measured first—a consequence of the commutative property.
