Accepted Answer

Option C. 10. Answer & Solution Answer: Option C Solution: & Distance = S_1 × S_2S_1 - S_2 × difference of time & 240 = S ( S - 8 )S - S + 8 × 1 & 240 × 8 = S × ( S - 8 ) & 48 × 40 = S × ( S - 8 ) & S = 48 km/hr . & = 48048 = 10 hrs

A covered a distance of 240 km at a certain speed. Had his speed been 8 km/h less, then the time taken would have been one hour more for covering the same distance. How much time (in hours) will he takes to cover a distance of 480 km at his original speed?
