A car is $4m$ long and a boat is $8m$ long. Find the length of car and boat altogether in feet. A) $12.00ft$ B) $25.5ft$ C) $39.37ft$ D) $40.3ft$
Hint: You should know the conversion of the unit. Like you should know $1m = 3.28ft$. You can use this and get your required answer. While substituting the values make sure that all the quantities have the same unit.
Complete step-by-step answer: Here in the question, it is given that the car whose length is $4m$ and the boat whose length is $8m$. And we need to calculate the total length, that means, Sum of length of car and length of boat ( in $ft$) So, first of all, we have to change the unit from $metre$ to $ft$. You must be knowing the value of unit changing for eg., $1m = 100cm$ Like this, $metre$ and $ft$ are also related. The relation is given by the equation $1m = 3.28ft$ So as we know that $1m = 3.28ft$, so we can find the length of car and boat in $ft$. So, let us calculate the required length. First we will convert the length of car in $feet$. Now according to question, length of car is given $4m$. As we know $1m = 3.28ft$, So, for $4m$, it will be $4m = 4 \times 3.28 = 13.12ft$ Now similarly we need to find the length of boat which is equal to $8m$ As we know $1m = 3.28ft$, We can find the measurement of $8m$in $ft$ as $8m = 8 \times 3.28 = 26.24ft$ Now we come to know that Length of car$ = 13.12ft$ Length of boat$ = 26.24ft$ Now we need to find the sum of length of car and boat in $feet$ $ = $length of car + length of boat $ = 13.12ft + 26.24ft \\ = 39.36ft \\ $ So, it is close to $39.37ft$, so our answer is option C.
Note: You must know the unit conversion. For example, $1m = 3.28ft$ $1m = 100cm$ And so on. This is all you should learn then you can solve these questions quickly and save your time.
