A car travels 120 Km in 3 hours find the distance travelled in 10 hours and how much time it takes to cover 30 kms with the same speed?

 Hi,

Distance travelled in 3 hrs = 120km

 "  " "  1 hr  = 1203

  = 40km

Distance travelled in 10 hrs = 40km x 10

 = 400km

Time taken to travel 120km = 3hrs

 "  " "  " 1km = 3120hrs

  = 140hrs

Time taken to travel 30km = 140 x 30

  = 34 hrs

=> Distance travelled in 10 hrs = 400km

  Time taken to travel 30km = 34hrs

Hope it Helps!!!!!!!

Cheers!!!!!
