# The tram traveled 100m at an average speed of 5m / s, and the next 600m at a speed of 10m / s.

The tram traveled 100m at an average speed of 5m / s, and the next 600m at a speed of 10m / s. Determine the average speed of the tram along the way?

The average speed of the tram along the entire route is calculated by the formula:

Vav. = S / t, where S is the path traveled by the tram (S = S1 + S2), t is the tram travel time (t = t1 + t2).

The first section of the tram track:

S1 = 100 m, V1 = 5 m / s, t1 = S1 / V1 = 100/5 = 20 s.

The second section of the tram track:

S2 = 600 m, V2 = 10 m / s, t2 = S2 / V2 = 600/10 = 60 s.

Let’s do the calculation:

Vav. = (S1 + S2) / (S1 / V1 + S2 / V2) = (100 + 600) / (20 + 60) = 700/80 = 8.75 m / s.

Answer: The average speed of the tram was 8.75 m / s.
