forward journey:
let speed be x km/hr and time be 7hrs
(i.e) Distance = speed * time => x*7=7x.....equ 1

Return journey:
speed increases by 12km/hr (ie) speed = x+12km/hr and
time =5 hrs
(i.e) Distance = speed * time => (x+12)*5=5x+60...equ 2

Equating 1 & 2 we get
7x=5x+60==> 2x=60=> x=30 means 30km/hr

Distance Travelled = speed * time ==> 30km/hr*7hrs=210 km
hence answer be 210 kms
