Question

Two cars are initially separated by 2500 m and traveling towards each other. One car travels at 4.5 m/s and the second car travels at 8 m/s. How long does it take for the two cars to meet

Answer 1

714.285s

Step-by-step explanation:

use relative velocity

8-4.5 = 3.5m/s

x = 2500m

2500/3.5 = 714.285s = 700s (with sig figs)
