The car covered 9 km in 10 minutes. What path will it cover in 0.5 hours, moving at the same speed?

We convert units of measurement to SI.

We convert time into seconds.

t1 = 10 * 60 = 600 s.

t2 = 0.5 * 60 * 60 = 1800 s.

We translate the path into meters.

S1 = 9 * 1000 = 9000 m.

Let’s find the speed of the car when it drove 9 km.

V = S1 / t1 = 9000/600 = 15 m / s.

Let’s find which way it will pass in 0.5 hours, moving at the same speed of 15 m / s.

S2 = V * t2 = 15 * 1800 = 27000 m.

27000 m = 27 km.

Answer: the car will cover the distance of 27 km at the same speed that it covered 9 km in 10 minutes.
