train A speed= 60km/h, B speed = 75km/h
A start = 8:30 , B start = 9:00
A cross = 60*1/2h
A cross distance = 60*1/2h = 30 km
(B–A) speed = (75–60) = 15km/h
B takes time to meet train A = 30/15 = 2 hours
distance from jaipur = 75*2 = 150km ans

Concept: Speed= Distance/Time

Given: First train starts at 8:30 a.m. with 60 km/hr speed.

Second train starts at 9 a.m. with 75 km/hr

Find: After how many kilometer they meet away from the Jaipur.

Solution:

Distance traveled by the train at 60 km/hr in 30 min =speed × time

                                                                              = 60× 30/60

                                                                              = 30 km

The distance of 30 km is to be covered with a relative speed of (75-60) km/hr is 15 km/hr.

Time taken to cover this distance = distance/speed

                                                        = 30/15

                                                        = 2 hour

Hence, the train will be together after 2 × 75 km/hr is 150 km from Jaipur.

Final answer: After 150 km both trains meet together.
