Average speed is the distance traveled by an object in total and divided by the amount of time an object covers the distance. The formula is -
Average speed = total distance traveled / total time taken
= 68km+64km / 2 hrs.+3hrs.
= 132km / 5hrs.
= 26.4km/hr.
Therefore, the train's average speed is 26.4km/hr.
<span>Lines a and b are parallel.
<a = 79
<b = 79
</span><d = 79
<z = 180 - 79 = 101
<y = 101

<c = 101
Answer:
Since the diameter of the pool is 10 feet, the radius will be one-half of the diameter.
The radius will be 5 feet.
The circumference of the pool will be Pi times the diameter.
The circumference will be Pi (3.14) times 10 feet.
The circumference will be 31.4 feet.
(-4) - (- 8) + (- 4)
- 4 - (- 8) + (- 4)
- 4 + 8 + (- 4 )
- 4 + 8 - 4
= 0
