Given : A car travelling at 60 km/hr

1 hr later another car travelling at 80 km/hr

We know : Distance = Speed × Time

And given : Second car started over the same road to overtake the first

Let Time take by second car to over take = t

So,

→ 80 × t = 60 × ( t + 1 )

→ 80 t = 60 t + 60

→20 t = 60

→ t = 3

Time take by second car to over take is 3 hour_____________(Ans.)
