Find the path if the body moves for 30 minutes at a speed of 72 km / h.

v = 72 km / h = (72 * 1000 m) / 3600 s = 20 m / s;

t = 30 min = 30 * 60 s = 1800 s;

S -?

Let us find the path according to the formula S = v * t, where S is the path, v is the speed, t is the time.

Let’s substitute the values of speed and time, let’s carry out calculations.

We get:

S = 20 m / s * 1800 s = 36000 m or 36 km.

Answer: the body has traveled 36,000 m or 36 km.
