Answer:
150 steps
Step-by-step explanation:
GOING UP:
Steps taken per second = speed = 3steps/s
Let Time taken = y
Number of steps = steps taken per second × time taken
Number of steps = 3 × y - - - - (1)
COMING DOWN:
Steps taken per second = 2steps/s
Total time taken = y + 25
Number of steps = 2 × (y + 25)
Number of steps = 2y + 50 - - - - - (2)
Equating (1) and (2)
3y = 2y + 50
3y - 2y = 50
y = 50
Substitute y = 50 into either (1) or (2)
Put y= 50 into (1)
Number of steps = 3y
Number of steps = 3(50)
Number of steps = 150
Volume formula: V = hwl
V = 3*3*4
V = 9*4
V = 36
Therefore, the volume is 36cm³
Best of Luck!
Answer:
(-1,6)
Step-by-step explanation:
y=-x+ 7
Let x = -1
y = -1+7
y = 6
