Question

Raju covers 10 m in 5 s and Sanju covers 20 m in 10 s. Who is faster?

• A. Raju is faster than Sanju.
• B. Sanju is faster than Raju.
• C. Both Raju and Sanju travel with same speed.
• D. Speed cannot be determined.

Answer 1

The correct option is C Both Raju and Sanju travel with same speed.

Given, distance covered by Raju = 10 m, time taken = 5 s,
Distance covered by Sanju = 20 m, time taken = 10s.
We know that,
$Speed=\frac{Distance}{Time}$
Speed of Raju = $\frac{10}{5}=2m{s}^{-1}$
Speed of Sanju = $\frac{20}{10}=2m{s}^{-1}$
Hence, both Raju and Sanju travel with the same speed.
