Question

Two cars are travelling at speeds of 60 km/hr and 75 km/hr. The second car is 3 km behind the first. How long will it take the 2nd car to overtake the first?

Answer 1

here i think we will use Distance = Rate times Time

Answer 2

the second car has rate 75 and so its distance will be \(75t\)
the first car has rate 60 and a 3km head start, so its distance is \(60t+3\)
when they meet the distances are the same, so you can solve by setting
\[75t=60t+3\] and solve the equation for \(t\)

Answer 3

you good from there?

Answer 4

Yes. so t = 1/5?

Answer 5

that is what i get, yes
one fifth of an hour, aka twelve minutes
