Question

12. A train covers 550km in 2 hours. What distance will it cover in 7 hours?

Answer 1

Let the distance covered in 7 h be = (x) km

{Assume that the train is in uniform motion}

The more the time goes, the more the train travels.

∴ This is a case of direction variation, where,

k = xy^-1 (Constant)

∴ 550/2 = x/7

{Numerator = Distance; Denominator = Time}

⇒275 × 7 = x

⇒x = 1925 km

Answer 2

Answer:

The answer to your question is 1925 km

Step-by-step explanation:

The train covers 550 km in 2 hours.

So,

Distance covered in 1 hour= 550/2

Distance covered in 7 hours= 550/2*7

= 1925 km
