Answer:
t = 20 s
Explanation:
145 m = 9 m/s × t – 35m
We can obtain the value of t in seconds by doing the following:
145 m = 9 m/s × t – 35m
Add 35 m to both side as shown below:
145 m + 35 m = 9 m/s × t – 35m + 35 m
180 m = 9 m/s × t
Divide both side by 9 m/s
t = 180 m / 9 m/s
t = 20 s
Therefore, the value of t is 20 seconds.
