is there a way that you can get average speed by adding distance 1 to distance 2 then divide by the time ?

Answer 1

The average speed for a journey of MANY legs is

Average speed = (Total distance travelled) /(Total time taken).

It doesn't depend on HOW MANY parts or subdivisions you break the journey into. Provided you can figure out both the total distance travelled, and the total time taken, you can work out your average speed by using the above formula.

The answer you want is the simplest application of this. If journey 1 does distance d1, and journey 2 goes a distance d2, the total distance travelled is (d1 + d2). If you DO know the individual times t1 anfd t2, the total time T is (t1 + t2), so:

average speed = (d1 + d2) / T = (d1 + d2) / (t1 + t2).

However, note that you don't HAVE to know the separate values of t1 and t2. For example, you night have forgotten to look at your watch at the end of journey 1. Not to worry: if you immediateltch at the end of the completed double journey, you STILL know the total time T, so can work out your average speed.

Live long and prosper.

Answer 2

yes you cover a total of 1+2 lets say a total of 15 miles in 15 minutes than you are traveling and average of 60 miles an hour.
that is saying you do not care to know how fast you were driving during leg 1 and leg 2.

Answer 3

thats exactly wut you ll get... distance A to B plus distance B to A devide by total time equals to average speed
