Question

Marco can swim at a speed of 45 meters per minute. To find how long it will take him to swim 200 meters, he solves the equation 45·t=200. what does t represent?

Answer 1

Answer:

t  represents the time Marco spent swimming on the pool at a speed of 45 meters per minute.

Step-by-step explanation:

The problem states the speed at which Marco is swimming, that is 45 meters per minute as well as the amount of meters he swims, that is, the distance Marco travels in the pool, 45 meters.

When Marco proposes the equation, he considers the speed at which he swims, the distance he travels and t represents in the equation the time it takes for Marco to travel the distance at that speed, because the general form of the formula to calculate the speed is given by the expression $speed=\frac{distance}{time}$.

And solving the Marco´s equation for t you have:

$45.t=200\\t=\frac{200meters}{45\frac{meters}{minute}}$

t=4 minutes

where 200 meters is the distance and 45$\frac{meters}{minute}$ is the speed.

Therefore t represents the time.

Answer 2

T stands for how long it takes him to swin 200 meters
