use this table of a school bus during morning pickups to answer the question. what is the average speed of the bus between 2.8 km and 4.2 km? 42 km/h 50 km/h 52 km/h 55 km/h
Answer
Answer:
50 km/h
Explanation:
Step1: Find the distance
The distance (d) is (4.2 - 2.8=1.4) km.
Step2: Find the time
The time (t) is (0.084 - 0.051 = 0.033) h.
Step3: Calculate the average speed
The formula for average speed (v=\frac{d}{t}). Substitute (d = 1.4) km and (t=0.033) h into the formula: (v=\frac{1.4}{0.033}\approx50) km/h.
