Question

Find the distance covered by a car moving at $20m/s$ for $3h$.

• A. $220km$
• B. $218km$
• C. $216km$
• D. $230km$

Answer 1

Answer: (C)

$216km$

Given speed of car = 20 m/s

Time taken = 3h

then

speed = $\frac{distance}{time}$

$20=\frac{D}{3\times 60\times 60}$

$D=2\times 3\times 6\times 6\times 1000$

$D=72\times 3km$

D= 216 km
