Question

Beth and Liz walk along a road toward each other, beginning

520 meters away from each other. Beth walks at 70 meters per
minute and Liz walks at 60 meters per minute. How far away
from each other are they 3 minutes after they start?

Answer 1

Let's start with the distance each person covers in 3 minutes.

Beth's distance = 70 meters/minute x 3 minutes = 210 meters

Liz's distance = 60 meters/minute x 3 minutes = 180 meters

Now we can find their distance apart after 3 minutes.

Distance apart = Initial distance - distance covered

Distance apart = 520 meters - (210 meters + 180 meters)

Distance apart = 520 meters - 390 meters

Distance apart = 130 meters

Therefore, Beth and Liz are 130 meters away from each other after walking towards each other for 3 minutes.
