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?
Answer & explanation
Correct answer: option 4
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
