If he goes by train more 80 km den the time increases 20 minute ..
if he goes less 80 km den ime decreases by 20 minute
120km bytrain+480km by car=8 hr
40km by train+560 km bycar=7hr 40 min
600 km bycar=7hr 30 min
car speed=80 km/hr
=>train speed =60 km/hr
if he goes less 80 km den ime decreases by 20 minute
