Answer:
The ratio of distances is 9:8
Step-by-step explanation:
Speed = Distance / Time
Distance = Speed * Time
For the first part of the journey
Speed = 30 kmph
Time = 3 hours
=> Distance = 30 * 3 km
= 90 km
For the second part of the journey
Speed = 40 kmph
Time = 2 hours
=> Distance = 40 * 2 km
= 80 km
Therefore:
Ratio of distances in the two parts = 90 km / 80 km
= 9/8
= 9:8
