Homework Answers
When two different speeds are given and these two different speeds are used to travel the same distance, then,
The formula for calculating avg speed is,
avg. speed = 2 * a * b / a + b
where a and b are the two speeds given in the question.
In our case, a = 37 mi/h and b = 71 mi/h
Therefore,
avg speed = 2 * 37 * 71/ 37 + 71
= 48.64 mi/h
Hence the avg speed of Steve during his entire journey is 48.64 mi/h.
