class 10 arithmetic chapter list
Answers
Step-by-step explanation:
Given That Trains Start at the Same Time.
Speed of 1st Train= 30 km/h
Speed of 2nd Train= 40 km/h
Let the time they meet Be= X
Train 2 travels X+30 more than T1. This is Speed of Train 2.
By Distance Formula:
Speed = Distance / Time
Time= X+30/40 --------------> (1)
Also, Time=X/30 ------------------> (2)
From Both the Equations:
X/30 = X+30/40
X x 40 = X+ 30 X 30
2X= 90/40
2X= 2.5
X= 1.25
Therefore, They meet After 1.25 Hrs.
