A man starts off on a journey. He travelled for 16 hours in total. First half of the distance was covered at 40 km/h and the second half at 60 km/h. What was the distance covered?

960 km

Let distance = 2D

According to question ,

\(\frac{D}{40}\) + \(\frac{D}{60}\) = 16 hours

\(\frac{5D}{120}\) = 16 hours

D = 16 × 24 = 384 km

2D = 2 × 384 = 768 km

So , Distance is 768 km
