Answer 2

Answer:

Distance is 2100 km.

Step-by-step explanation:

Since we have given that

Let the time be 't'.

If speed = 30km/hr

Then it takes 10 minutes late

If speed = 42 km/hr

Then, it takes 10 minutes early.

According to question, it becomes,

30(t+10)=42(t−10)

30t+300=42t−420

42t−30t=300+420

12t=720

t=60

So, the distance would be

30(60+10)

=30×70

=2100 km
