Two cyclists started moving towards each other at the same time along the highway between the two cities. speed of one cyclist 220m / min. and the second 250 m / min how close the cyclists will be to each other in 30 minutes

1. Let us express the speed of convergence of cyclists:
250 + 220 = 470 (m / min);
2. Let’s translate all values in km / h or hours:
250 m / min = 15 km / h;
220 m / min = 13.2 km / h;
470 m / min = 28.2 km / h;
30 minutes = 0.5 hours;
3. The expression for the approach speed will be written as follows:
13.2 + 15 = 28.2 (km / h);
4. Let us express the distance that cyclists will approach in 30 minutes:
28.2 * 0.5 = 14.1 (km / h);
5. Let’s write down the general expression:
(13.2 + 15) * 0.5;
Answer: the required expression: (13.2 + 15) * 0.5 (km).
