An ant can travel at a constant speed of 980 inches every 5 minutes. At this rate, how far can the ant travel in 7 minutes?
Zarrin [17]

Answer:

1372\: \mathrm{inches}

Step-by-step explanation:

Since the ant travels at a constant speed, we can set up the following proportion:

\frac{980}{5}=\frac{x}{7}, where x is the distance the ant can travel in 7 minutes.

Solving for x, we get:

x=\frac{7\cdot980}{5}=\fbox{$1372\:\mathrm{inches}$}.
