Question

if you traveled the first 150km in 2.5 hours ,and the second part of the trip,100km in 1.4 hours.what w your average speed

Answer 1

The average speed of the travel was 64.1 km/h.

Step-by-step explanation:

We can calculate the average speed of the travel as:

s = (s₁ + s₂) / n = (150 km/h + 100 km/h) / 2 = 250 km / 2 = 125 km/h

where:

s: average speed of the entire travel

s₁: average speed of the first part of the trip

s₂: average speed of the second part of the trip

n: number of parts of the trip
