In 1 hours it goes 70km, after every 2 hours it increases it speed by 10 km /hr
In 2 hour =140km
In next 2 hour =290km
In next 1 hours =360km
Now 360 km =5hours
1km =5/360
345km=5/360*345
=24*6+1
In 2 hour =140km
In next 2 hour =290km
In next 1 hours =360km
Now 360 km =5hours
1km =5/360
345km=5/360*345
=24*6+1
