Answer:
ummmmmmmmm hard to say
Step-by-step explanation:
To solve this, add 17 to both sides:
x = -25 + 17
x = -8
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.
