Jeetu traveled $21\ km\ 245\ m$ by bus, $15\ km\ 632\ m$ by car and walked $351\ m$ by how many km did he travel altogether.a. $36\ km\ 228\ m$.
b. $35\ km\ 228\ m$.
c. $34\ km\ 228\ m$.
d. $37\ km\ 228\ m$.

Given: Jeetu traveled $21\ km\ 245\ m$ by bus, $15\ km\ 632\ m$ by car and walked $351\ m$.

To do: To find the total distance travelled by Jeetu.

Solution:

Distance travelled by bus$=21\ km\ 245\ m$

Distance travelled by car$=15\ km\ 632\ m$

Distance travelled by walk$=351\ m$

Therefore, total distance by Jeetu$=21\ km\ 245\ m+15\ km\ 632\ m+351\ m$

$=( 21+15)km+( 245+632+351)m$
 

$=36\ km+ 1228\ m$

$=36\ km+1000\ m+228\ m$

$=36\ km+1\ km+228\ km$                           [$\because 1000\ m=1\ km$]

$=37\ km+228\ m$

Thus, option $( d)$ is correct.
