Step-by-step explanation:
You are solving the problem 4 x 3. This is really another way to say "3 groups of four."<span>You can think of this as repeated addition, where the number four will be repeated 3 times. But you are adding the number the amount of times you want to multiply it by.</span>
1/10 = 0.1 meters per second.
Then just divide 5 by 0.1 and you get 50 seconds.
