Question

Convert the given units:
a) 10 $hours$ into $\min $
b) 8 $hours$ $56\min $ into $\min $
c) 16 $hours$ $43\min $ into $\min $
d) 3 $days$ $12\,hours$ $25\min $ into $\min $
e) 2 $days$ into $\min $

Answer 1

Hint: To solve this kind of question firstly, we will identify which unit is the upper unit and which one is the lower unit then we will convert the upper unit into a smaller one. For example, to convert days into minutes, first of all, we will convert days into hours then we will convert these hours into minutes.

Complete step-by-step answer:
a) 10 $hours$ into $\min $
As we know that one hour equals $60\min $, we can write the equation below.
$1hour = 60\min ......(1)$
We need to find the $10\,hours$ in $\min $
We multiply equation $(1)$ with $10$
Then, $10\,hours = 10 \times 60\min $
Hence,$10\,hours = 600\min $

b)$8\,hours$ $56\,\min $ into $\min $
As we know that one hour equals $60\min $, we can write the equation below.
$1\,hour = 60\min ......(1)$
We want $8\,hours$ in $\min $
We multiply equation $(1)$ with $8$
Then, $8\,hours = 8 \times 60\min $
$8\,hours = 480\min $
As per the question, we need to find $8\,hours$ $56\,\min$ into $\min$, so we just add $56\,\min$ into converted form of $8\,hours$
Hence, $8\,hours$ $56\,\min = 480 + 56\min = 536\min $

c)$16\,hours$ $43\,\min$ into $\min $
As we know that one hour equals $60\,\min $, we can write the equation below.
$1\,hour = 60\,\min ......(1)$
We want $16\,hours$ in $\min $
We multiply equation $(1)$ with $16$
Then, $16\,hours = 16 \times 60\min $
$16\,hours = 960\min $
As per the question, we need to find $16\,hours$ $43\,\min$ into $\min$, so we just add $43\,\min$ into converted form of $16\,hours$
Hence, $16\,hours$ $43\min = 960 + 43\min = 1003\min $
$3\,days$ $12\,hours$ $25\min $ into $\min $
As we know that one day is equal to $24\,hours$, we can write the equation below.
$1\,day = 24hours......(1)$
We want $3\,days$ in $hours$
We multiply equation $(1)$ with $3$

d) $3\,days = 3 \times 24hours = 72\,hours$
As per the question, we need to find $3\,days 12 hours$ into $hours$, so we just add $12\,hours$ into converted form of $3\,days$
$3\,days$ $12\,hours = 72 + 12hours = 84\,hours$
As we know that one hour equals $60\min $, we can write the equation below.
$1\,hour = 60\min ......(2)$
We want $84\,hours$ in $\min $
We multiply equation $(2)$ with $84$
Then, $84\,hours = 84 \times 60\min = 5040\min $
As per the question, we need to find $84\,hours$ $25\min$ into $\min $, so we just add $25\min $into converted form of $84\,hours$
Hence, 3 $days$ 12 $hours$ $25\min $$ = 5040 + 25\min = 5065\min $
2 $days$ into $\min $
As we know that one day is equal to 24 $hours$, we can write the equation below.
$1day = 24\,hours......(1)$
We want 3 $days$ in $hours$
We multiply equation $(1)$ with $2$
$2\,days = 2 \times 24hours = 48 hours$
As we know that one hour equals $60\min $, we can write the equation below.
$1hour = 60\min ......(2)$
We want 48 $hours$ in $\min $
We multiply equation $(2)$ with $48$
Hence, 48 $hours = 48 \times 60\min = 2880\min $

Note: We should know the relation between the smaller units and upper units so that we can use these relationships to convert upper units into lower units as our requirements, and one more thing we should note that we can’t add or subtract different units. Only similar units can perform addition and subtraction.
