The electric locomotive moves at a speed of 80 km / h. Which way will he go in 30 minutes?

Given:

V = 80 kilometers per hour – the speed of the electric locomotive;

t = 30 minutes – time span.

It is required to determine which path S (kilometers) the electric locomotive will cover during the time interval t.

Since 1 hour = 60 minutes, then:

t = 30 minutes = 30/60 = 0.5 hours.

Then the path traveled by the electric locomotive will be equal to:

S = V * t = 80 * 0.5 = 40 kilometers.

Answer: an electric locomotive will cover a distance of 40 kilometers in 30 minutes.
