Answer:
The average speed is = 11.1m/s
Explanation:
Recall that average speed is defined as the total distance traveled with respect to the total number of time, therefore we say that the total distance traveled is 40Km according to your question, remember, the unit of speed is metre per second, so you change 40km by multiplying it with 1000, recall that, 1000m = 1km, so 40km×1000m = 40,000m, also 1h= 60×60, =3600s
Remember the formula for average speed is = Total distance traveled÷ total time taken
Thus; 40000m/3600s
Then we had, 11.1m/s...
