Question

A school bus travels distance of 30 km in 1 hour. How much time it will take to travel distance of 90 km.​

Answer 1

Answer:

3 hours it was very simple answer

Answer 2

Answer:

3 hours

Step-by-step explanation:

distance travelled is directly proportional to the required time.

Thus,

$\frac{30}{1} = \frac{90}{x}$

$30x = 90$

$x = \frac{90}{30}$

$x = 3$

And thus the required time is 3 hours.
