Question

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

Explanation:

Step1: Calculate the distance

The distance \(d\) is \(4.2 - 2.8=1.4\) km.

Step2: Calculate 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: \(v=\frac{1.4}{0.033}\approx42.42\approx42\) km/h (rounded to the nearest whole number as per the options).

Answer:

42 km/h
