Question

If a car covers an distance of 81 km in 9 hours,how much distance car will cover in 30 minutes with the same speed .​

Answer 1

1 hour=60 minute

9 hour=60×9 minutes

9 hour=540 minutes

$\frac{81}{540} = \frac{x}{30}$

$\frac{81 \times 30}{540} = x$

$\frac{81}{18} = x$

4.5=x

Therefore,the car will travel 4.5 km in 30 minutes with same speed
