At 8:00 a.m., there were t inches of snow on the ground. At 5:00 p.m., there were 3t inches of snow on the ground. How many more inches of snow were on the ground at 5:00 p.m. than at 8:00 a.m. if there were 12 inches of snow on the ground at 5:00 p.m.?

Sagot :

we conclude that at 5:00 p.m. there are 8 more inches of snow than at 8:00 a.m.

How many more inches of snow were on the ground at 5:00 p.m. than at 8:00 a.m.?

We know that at 8:00 a.m. there were t inches of snow in the ground.

At 5:00 p.m. there were 3t inches of snow in the ground.

Then the difference between the heights of the snow is:

3t- t = 2t

And we know that at 5:00 p.m. there were 12 inches of snow then we can solve the linear equation for t:

3t = 12in

t = (12in)/3 = 4 in

Replacing that in the difference of heights:

2t = 2*4in = 8in

From this, we conclude that at 5:00 p.m. there are 8 more inches of snow than at 8:00 a.m.
