The distance travelled by a person varies directly with the duration of the journey. If the person travels 784 km in 14 hours, in how many hours will the person cover 1120 km?
Answer & explanation
Correct answer: option 3
When speed is constant then distance is directly proportional to time.
Hence,
Speed in both case is same, therefore,
⇒ \(\frac{784}{14}\) = \(\frac{1064}{T}\)
⇒ T = \(\frac{1120}{56}\)
⇒ T = 20 hours
