The travel time t is inversely proportional to the speed s of the vehicle. If a car is travelling at an average speed of 80 kph, it will take 4 hours to complete its journey. How fast should the car travel if it must complete the journey in 3 hours?​

Sagot :

Answer:

To find the distance, multiply speed and time.

d = st, s = 80, t = 4

d = 80(4)

d = 320km

Now, calculate for the speed.

s = d/t

s = 320/3

s = 106.6666667

≈ 106.7 km/h (final answer)

Hope this helps. ^^
