Answer 2

Answer:

Given:

Distance travelled by the car in 11 hours = 880 km

Time taken by the car for travelling 250 km

$= x \: hours$

We know that,

$11:x::880:250 \\ ⇒\frac{11}{x} = \frac{880}{250} \\ ⇒ \frac{11}{x} = \frac{88}{25} \\ ⇒88x = 11 \times 25 \\ ⇒x = \frac{11 \times 25}{88} \\ = \frac{275}{88} \\ = 3.125$

∴ The car would take 3.125 hours for travelling 250 km.
