Download Solution PDFGiven
Speed= 25 km/h
Speed increased = 15 km/h
Formula used
Time = Distance/Speed
Calculation
Distance covered by Karan is x km
Time = x/25
Distances covered by Karan when speed increases = (x + 90) km
Time = (x + 90)/40
⇒ x/25 = (x + 90)/40
⇒ 40x = 25x + 2250
⇒ 15x = 2250
⇒ x = 2250/15
⇒ x = 150 km
∴ Karan travelled a distance of 150 km.
