Answer:

72km/h

Step-by-step explanation:

Bus - 45 mins at 40km/h

Car - 25 mins at ?

First, find the distance travelled by the bus (since, the journey of the two vehicles are the same, the distance would be the same as well)

  • distance = speed × time
  • distance = 40 × 3/4 (45 mins = 3/4 of an hour (45 ÷ 60))
  • distance = 30km

Now we can find the speed of the car using the equation

  • speed = distance ÷ time
  • speed = 30 ÷ 5/12 (25 mins = 5/12 of an hour (25 ÷ 60))
  • speed = 72km/h
