Which is traveling faster: Traveling 150 yards in 40 seconds or traveling 40 yards in 16 seconds?

We can find out how far each travels in one second by dividing the distance by the time taken.

$${\frac{{\mathtt{150}}}{{\mathtt{40}}}} = {\frac{{\mathtt{15}}}{{\mathtt{4}}}} = {\mathtt{3.75}}$$

$${\frac{{\mathtt{40}}}{{\mathtt{16}}}} = {\frac{{\mathtt{5}}}{{\mathtt{2}}}} = {\mathtt{2.5}}$$

150 yards in 40 seconds is faster because in one second, you travel 3.75 yards, but 40 yards in 16 seconds is only 2.5 yards a second.

150/40 = 15/4 = 3.75

40/16 =  5/2 = 2.5

The first thing is faster
