Answer / manas
let car speed =x
after 7 hour journey the car cover all distance
means Distance= Speed*time=7x km
in the return journey that car increase speed 12km/hour
cover same distance in 5 hours
maans distance=(x+12)*5 km
both case distance is same
7x=(x+12)*5
=>7x=5x+60
=>2x=60
=>x=30km/hour
speed=30km/hour
distance=30*7=210km
