elljksjjsis Let's start by finding out how fast the two runners are moving towards each other. We can do this by adding their speeds together:

2 m/sec + 1.5 m/sec = 3.5 m/sec

So the runners are moving towards each other at a combined speed of 3.5 m/sec.

The distance between the runners is 210 meters, and they are moving towards each other at a combined speed of 3.5 m/sec. We can use the formula:

time = distance / speed

to find out how long it will take for them to meet.

time = 210 m / 3.5 m/sec

time = 60 seconds

So the two runners will meet after 60 seconds.
