Question

A racing car covered $600km$ in $3$ hours $20$ minutes. Find its speed in metre per second.How much distance will the car cover in $50$ sec ?

Answer 1

Distance covered by car $=600km$

$\Rightarrow 1km=1000m$

$=6,00,000m$

$\Rightarrow$ Time taken $=3hour20minutes$

$=(3\times 3600sec)+(20\times 60sec)$

$=12,000sec$

$\Rightarrow$ Speed in m/s $=\frac{6,00,000}{12,000}$

$=50m/s$

Now distance travelled in $50seconds$

$\Rightarrow D=S\times T$

$=50s\times 50m/s$

$\Rightarrow D=2,500m$

Hence, solved.
