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
