Answer 1

Altogether Jeetu had travelled → option (4): 37 km 228 m.

-----------------------------------------------------------------------------------

Let's understand a few concepts:

To solve the given problem we will use the following conversion rate:

$\boxed{\bold{1 \:kilometer = 1000 \:meter}}$

OR

$\boxed{\bold{1 \:meter = \frac{1}{1000} \:kilometer}}$

--------------------------------------------------------------------------------------

Let's solve the given problem:

By using the above conversion rate we will convert each of the distances travelled into kilometers:

$21\: km \:245\: m = 21\: km + \frac{245}{1000} km = 21 \:km + 0.245\: km = 21.245\:km$

$15\: km \:632\: m = 15\: km + \frac{632}{1000} km = 15 \:km + 0.632\: km = 15.632\:km$

$351\:\:m= \frac{351}{1000}\: m =0.351\:km$

So,

The distance travelled by bus = 21.245 km

The distance travelled by car = 15.632 km

The distance travelled by walking = 0.651 km

Therefore,

The total distance travelled by Jeetu altogether,

=  $21.245 \:km+ 15.632\:km+0.651\:km$

= $37.228 \:km$

= $37 \:km+0.228\:km$

= $37 \:km+\frac{228}{1000} \:km$

• since $\frac{1}{1000}\:km = 1 \:m$

= $\bold{37 \:km\:228\:m}$ ← option (4)

Thus, Jeetu altogether had travelled 37 km 228 m.

Answer 2

Concept: Meter is the SI unit of the distance. It is denoted as 'm'.

Kilometer is the largest SI unit of the distance. It is denoted as 'km'.

Given: Distance traveled by bus=21 km 245 m

           Distance traveled by car=15 km 632 m

           Distance traveled on foot=0 km 351 m

Find: Find the total distance traveled by Jeetu?

Solution: Total distance=distance by bus+distance by car+distance on foot

                Total distance=21 km 245 m+15 km 632 m+0 km 351 m

                Total distance=37 km 228 m

Final answer: Total distance traveled by Jeetu is 37 km 228 m.
