Question:

Four students like cross country running. Every day, Asha runs 4.25 km in the morning and 2.5 km in the evening, Bhavin runs 4.14km in the morning and 2.34 km in the evening, Cherian runs 3.5 km in the morning and 3.75 in the evening, And Daya runs 4.14 km in the morning and 2.14 km in the evening. Who runs the greatest distance daily?

_____________________________________

Given:

1) Distance covered by Asha:

• In morning - 4.25 km
• In evening - 2.5 km

2) Distance covered by Bhavin:

• In morning - 4.14 km
• In evening - 2.34 km

3) Distance covered by Cherian:

• In morning - 3.5 km
• In evening - 3.75 km

4) Distance covered by Daya:

• In morning - 4.14 km
• In evening - 2.14 km

What to do?

• We're asked to find who runs the greatest daily.

‎ ‎ ‎

Solution:

To find the answer, first we've to sum up each person's distance covered by him/her in the morning and in the evening.

$\large\underline{\boxed{\tt{\green{Case\:I-\:Asha}}}}$

As we know, 1 km = 1000 m

$\implies{\sf{4.25\:km=4.25\times1000}}$

$\sf = 4250\:metres.$

$\implies{\sf{2.5\:km=2.5\times1000}}$

$\sf = 2500\:metres.$

$\large{\bold{\red{Sum}}}$$\rightarrow$$\sf 4250+2500$

$\sf =6750\:metres=6.75\:km$

‎ ‎ ‎

$\large\underline{\boxed{\tt{\green{Case\:II-\:Bhavin}}}}$

As we know, 1 km = 1000 m

$\implies{\sf{4.14\:km=4.14\times1000}}$

$\sf = 4140\:metres.$

$\implies{\sf{2.34\:km=2.34\times1000}}$

$\sf = 2340\:metres.$

$\large{\bold{\red{Sum}}}$$\rightarrow$$\sf 4140+2340$

$\sf =6480\:metres=6.48\:km$

‎ ‎ ‎ ‎

$\large\underline{\boxed{\tt{\green{Case\:III-\: Cherian}}}}$

As we know, 1 km = 1000 m

$\implies{\sf{3.5\:km=3.5\times1000}}$

$\sf = 3500\:metres.$

$\implies{\sf{3.75\:km=3.75\times1000}}$

$\sf = 3750\:metres.$

$\large{\bold{\red{Sum}}}$$\rightarrow$$\sf 3500+3750$

$\sf =7250\:metres=7.25\:km$

‎ ‎ ‎ ‎

$\large\underline{\boxed{\tt{\green{Case\:IV-\:Daya}}}}$

As we know, 1 km = 1000 m

$\implies{\sf{4.14\:km=4.14\times1000}}$

$\sf = 4140\:metres.$

$\implies{\sf{2.14\:km=2.14\times1000}}$

$\sf = 2140\:metres.$

$\large{\bold{\red{Sum}}}$$\rightarrow$$\sf 4140+2140$

$\sf =6280\:metres=6.28\:km$

‎ ‎ ‎ ‎ ‎

Answer:

• ‎$\large{\underline{\bold{\blue{Cherian}}}}$ covers the greatest distance daily.

‎

• Because, 7.25 (Cherian) > 6.75 (Asha) > 6.48 (Bhavin) > 6.28 (Daya)

‎ ‎

• $\normalsize{\boxed{\sf{Option:C\: is\:correct}}}$
