Vivek starts moving at the speed of 70 km/hr at 8:00 am. Neeraj starts moving in the same direction after 4 hours of Vivek at the speed of 120 km/hr. Which of the following statement(s) is/are correct ?

I. Neeraj and Vivek meet each other at 5:36 pm.

II. Total distance covered by both Neeraj and Vivek till 4 pm is 1080 km.

Only I

I. Neeraj and Vivek meet each other at 5:36 pm.

Distance covered by Vivek in 4 hours = 70 × 4 = 280 km

Relative speed ( when moves in same direction ) = 120 - 70 = 50 km/h

Time taken = \(\frac{280}{50}\) = 5.6 hours

= 5 hours 36 minutes

So , both Neeraj and Vivek meet at 5:36pm

Statement I is correct .

II. Total distance covered by both Neeraj and Vivek till 4 pm is 1080 km.

Distance covered by Vivek till 4:00 pm = 70 × 8 =  560 km

DIstance covered by Neeraj till 4:00 pm = 120 × 4  = 480 km

So , Total distance traveled by both both = 560 + 480 = 1040 km

So , Statement 2 is incorrect .

Ans :- Only I
