Question

A car covers 450 km in 9/2 hours how much time will take in covering 350 km

Answer 1

Answer:  $\frac{7}{2}$ hours or $3\frac{1}{2}$ hours

Step-by-step explanation:

We know that ,

Speed = Distance

               Time

So,

$\frac{450}{\frac{9}{2} } =$ 450 ÷ $\frac{9}{2}$ = 450 x $\frac{2}{9}$ = 100km/h

Now Time= Distance

                    Speed

$\frac{350}{100} = 3.5 hours$

or $\frac{7}{2}$ hours or $3\frac{1}{2}$ hours
