Question

Using the following equation, find in seconds 145m = 9 m/s x t-35m

Answer 1

t = 20 s

Step-by-step 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.
