Question

A rabbit’s hop is $2m$ long. How many hops does a rabbit take to travel $1\text{km}$?[ Hint: Convert km into m first]

Answer 1

Hint: To solve this question we need to have the knowledge of division and word problems. So the first step to solve the question will be to convert the unit of the distance into the same unit that is either in kilometers or in meters. The second step will be to divide “the total distance travelled” by “the distance covered in rabbit’s one hop” so that we can find the value for the number of hops.

Complete step by step answer:
The question asks us to find the number of hops that a rabbit requires to travel one kilometre ($1\text{km}$) when each hop covers $2m$. The first time will be to convert the kilometre unit into metre. For doing this we should know that 1 kilometre is equal to 1000 meter, which in mathematical form is written as:
$\Rightarrow 1\text{ kilometer = 1000 meter}$
According to the question demand, the rabbit has to travel $\text{1000 meter}$as in the question the distance travelled is$1\text{km}$.
Now we will move to the second step. Considering the distance covered by rabbit in one hop is $2m$ then the number of hops done by rabbit to travel $\text{1000 meter}$will be equal to “Total distance travelled by the rabbit” by “Distance travelled by the rabbit in one hop”. Then the number of hops does the rabbit take will be written as:
$\Rightarrow \dfrac{\text{Total distance travelled by the rabbit}}{\text{Distance travelled by the rabbit in one hop}}$
$\Rightarrow \dfrac{1000}{2}$
On calculating the above fraction and bringing in its lowest form, we get:
$\Rightarrow 500$
$\therefore $ A rabbit’s hop is $2m$ long, so to travel $1\text{km}$it has to take $500$ hops.

Note: We can check whether the answer is correct or not, by multiplying the number of hops to the distance covered by rabbit in one hop. If the total distance travelled comes the same as that given in the question then the answer we get is correct.
$\Rightarrow 2m\times 500$
$\Rightarrow 1000m$
Now we will convert the distance in meters to kilometers. So the distance we get:
$\Rightarrow \text{1 km}$
Since the answer we got is the same as the question which is $\text{1 km}$, so the answer we got is correct.
