Question

Ram is traveling by car at a rate of 40 kmph. After 80 km he rests for 20 minutes. How long will he take to cover a distance of 240 kms?

Options

• 6 hrs 40 min

• 6 hrs 11 min

• 5 hrs 11 min

• 7 hrs 15 min

Answer 1

6 hrs 40 min

Explanation:

Total Distance Travelled = 240 km

Speed = 40 kmph

Time is taken`=240/40` = 6 hr ...... `(∵"T" ="D"/"S")`

After 80 km he stops for 20 minutes

then no. of stoppages`=240/80=3`

But on the last stoppage, he will arrive at his destination

For 2 stoppages time taken = 2 × 20 = 40 min

So, total time is taken = 6 hr 40 min
