Let the distance of Vishal travelled by x km and by aeroplane y km
total distance = 1900 km
As pe first condition
x + y = 1900 ----- 1
The speed of the bus 60 km/hr
The speed of the aeroplane 700 km/hr
Time = distance/ speed
as per second condition
x/60 + y/700 = 5
multiply eq by 4200
70x + 60y = 2100------2
multiply eq 1 by 6
6x + 6y = 11400-------3
Subtract eq 3 from 2
64x = 9600
x = 150 km/hr
Vishal travelled by bus the distance is 150 km/ hr
total distance = 1900 km
As pe first condition
x + y = 1900 ----- 1
The speed of the bus 60 km/hr
The speed of the aeroplane 700 km/hr
Time = distance/ speed

Hey buddy unit is km.Not km/hr
