Question

A van travels with a constant speed of 65 km per hour for 24 km and another 50 km with a constant speed of 80 km per hour how long it will take for this trip

Answer 1

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.
