Hey
let x km be the distance travel by bus and
y k.m be the travel by aeroplane
total distance = 1900 km
from first condition
x+y=1900..............(1)
now time = distance / speed
from second condition
x/60 + y/700=5 .............(2)
solve two equations
i hope its help you

Given:
Total distance = 1900 km
Distance by bus = bus km
Distance by airplane = ( 1900 - bus ) km
Total time = 5 hrs
Speed of the bus = 60 km / hr
Speed of the airplane = 700 km / hr
To find:
The distance traveled by bus.
Solution:
Time traveled in bus = Bus / 60
Time traveled in airplane = ( 1900 - bus ) / 700
Total time = Time traveled in bus + Time traveled in airplane
Total time = Bus / 60 + ( 1900 - Bus ) / 700
Substituting,
Bus / 60 - Bus / 700 + 1900 / 700 = 5
( 35 * Bus - 3 * Bus ) / 2100 = 5 - 19 / 7
32 * Bus = 2100 * ( 35 - 19 ) / 7
32 * Bus = 300 * 16
Bus = 4800 / 32
Hence,
Bus = 150 km
