Question

The two clocks show the time taken by SIdak for a walk in the park in the morning. How long did she walk?

A. 60 minutes
B. 70 minutes
C. 30 minutes
D. 80 minutes

Answer 1

Hint: First we will calculate the difference in time between the clock when he started walking and the clock when he completed walking and convert the time from hours into minutes to find the required value.

Complete step by step answer:

We are given that SIdak started her walk in the park in the morning at \[6:00\] from the left clock and completed her walk in the park in the morning at \[7:10\] from the right clock.

We will now calculate the time he took to complete his walk by subtracting the time he started his walk from the time he completed his walk, we get

\[ \Rightarrow 7:10 - 6:00 = 1:10\]

Thus, the time taken by Sidak to complete his walk is 1 hour 10 minutes.

We know that 1 hour has 60 minutes, we have \[1{\text{ hr}} = 60{\text{ min}}\].

Converting the above time taken by Sidak to complete his walk-in minutes, we get

\[
   \Rightarrow 1 \times 60 + 10 \\
   = 60 + 10 \\
   = 70{\text{ min}} \\
 \]
Therefore, Sidak was walking in the park for 70 minutes.
Hence, option B is correct.

Note: In solving these types of questions, the student should be careful that for every number 1 to 12, each number has 5 minutes. Since the minute hand is at 2, so there are 10 minutes. We have to convert the final answer in minutes to find the required value, or else the answer will be wrong.
