Question

If a man travels at a speed of 30km/h, he reaches his destination 10 minutes late and if he travels at a speed of 42 km/h, he reaches his destination 10 minutes early. What is the distance?

Answer 1

35 kilometres........

Answer 2

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

$30(60+10)\\\\=30\times 70\\\\=2100\ km$

Hence, distance is 2100 km.
