P. 2
Example 2: What is the value of B in given problem?
48 hours 30 minutes = B hours 90 minutes
In order to get the answer we need to do the following steps:
Step 1: In both the sides of the problem, we have the values of minutes.
Step 2: The value of minutes in Left Hand Side (LHS) of the problem is smaller
than that in Right Hand Side (RHS).
30 minutes < 90 minutes
We know that, 60 minutes = 1 hour
Now we borrow 1 hour from 48 hours in LHS,
48 hours 50 minutes = 48 hours + 30 minutes
= 47 hours + 1 hour + 30 minutes
= 47 hours + 60 minutes + 30 minutes
= 47 hours + 90 minutes
= 47 hours 90 minutes.
Therefore, the required answer is 47.
Example 3: What is the value of x in given problem?
x hours 80 minutes = 4 hours 140 minutes
In order to get the answer we need to do the following steps:
Step 1: In both the sides of the problem, we have the values of minutes.
Step 2: The value of minutes in Left Hand Side (LHS) of the problem is smaller
than that in Right Hand Side (RHS).
80 minutes < 140 minutes
