Answer:
It will take 1 hour approx fro the trip.
Step-by-step explanation :
For the first 24 km,
Speed = 65 km / hr
Time taken = Distance / speed
⇒ Time = 24 / 65
For the next 50 km,
Speed = 80 km /hr
⇒ Time taken = Distance / speed
⇒ Time = 50 / 80
Total time taken
⇒ 24 / 65 + 50 / 80
⇒ 384 + 650 / 1040
⇒ 1034 / 1040
⇒ 0.99
⇒ 1 hour ( approx )
Hence, it will take 1 hour approx for the trip.
