Answer 1

Answer:-

390

Solution :-

Total time of journey = 8 hours

First half of journey = Second half of journey

= 8/2 = 4 hour

Now, speed= distance travelled/time taken

Since we already know speed and time taken,we can put that equation like this,

Distance= Speed x time taken

Since the journey has two halves with different speed,

Total distance = Distance travelled in first half+Distance travelled in second half

=>Total distance = (30 x 4) + (50x 4)

= 120+200

=320kms
