Answer 2

Calculation of Shopping Time in Saturday and Sunday

To calculate the time required for shopping on Saturday, we need to compare it with the time required on Sunday. Let's assume that the time required for shopping on Sunday is 2 hours more than the time required on Saturday.

Let's represent the time required for shopping on Saturday as x minutes. According to the given information, the time required for shopping on Sunday is x + 2 hours.

To convert the time from hours to minutes, we multiply the number of hours by 60. Therefore, the time required for shopping on Sunday is (x + 2) * 60 minutes.

Now, we can set up an equation to solve for the value of x:

x + 2 = 4x

Simplifying the equation:

2 = 3x

Dividing both sides of the equation by 3:

x = 2/3

Therefore, the time required for shopping on Saturday is 2/3 of an hour, which is equivalent to 40 minutes.

So, your grandmother can complete the shopping on Saturday in 40 minutes.
