Rajesh drove at the speed 100 km/hr from his home to a resort. While returning he got struck in traffic and took 6 more hrs; he could drive only at the speed of 40 km/hr. How many kilometer did he drive each way?
Let the distance be x km. Then, x/40 × x/100 = 6 5x – 2x = 6 × 200 3x = 1200 x = 400 km
