A man travelled a distance of 1200 km in 16 hours. He travelled partly by car at a speed of 40 km/h, and partly by train at a speed of 80 km/h. What is the distance travelled by car?

80 km

We know that ,

Speed = \(\frac{Distance}{Time}\)

= \(\frac{1200}{16}\)

= 75 km/h

According to question,

( 1 + 7 )R = 16 hours

8R = 16 hours

1R = 2 hours

Time taken  by car to travel = 1 x 2 = 2 hours

We know,

Distance = Speed x Time

= 40 x 2

= 80 km
