Within a time interval of 1.0 min, the bus was moving at a speed of 60 km / s, and then, for a time interval of 4.0 min, at a speed of 40 km / h. Determine the average speed of the bus along the entire route.
Initial data: the first time interval (t1 = 1 min (1/60 h); V1 = 60 km / h); second time interval (t2 = 4 minutes (4/60 h); V2 = 40 km / h).
The average speed of the bus on all routes is determined by the formula: Vav. = S / t = (S1 + S2) / (t1 + t2) = (V1 * t1 + V2 * t2) / (t1 + t2).
Calculation: Vav. = (60 * 1/60 + 40 * 4/60) / (1/60 + 4/60) = 44 km / h.
Answer: The average speed of the bus along the entire route is 44 km / h.
