A bullock cart covers a distance of 15.50 km in 2 hours. In approximately how much time will it cover a distance of 12.85 km?

(Hint: Speed=distance/time)

Please help guys.Its very urgent.

Answer :

tanishqsingh
distance travelled =15.50 km
time taken=2 hr
so the speed is 15.50/2 km/hr
time taken to cover 12.85 km=(12.85/15.50)*2=1.65 hrs 
                                                                  approx=1 hr 39 min

u can do it with the direct variation method........

Distane(in km)           15.50                12.85
Time (in hrs)                2                      y2  
  ⇒         15.50    =   12.85
               2                y2
⇒ y2  x  15.50   =   12.85  x  2
⇒ y2  =  12.85  x 2
                  15.50
⇒  1  102     (ans is in mixed fraction)
          155
