The two ships left towards each other at 8 o’clock and met at 13 o’clock on the same day.

The two ships left towards each other at 8 o’clock and met at 13 o’clock on the same day. At 8:00 the distance between them was 290 km. One motor ship sailed at a speed of 28 km / h. At what speed was the other ship sailing?

Let’s solve this task in steps and explain each of them in detail.
1) 13 – 8 = 5 hours – this is the time the two ships were on the way, as they left towards each other at 8 o’clock and met at 13 o’clock on the same day;
2) 28 * 5 = 140 kilometers – the distance that the first motor ship sailed at a speed of 28 kilometers per hour in 5 hours;
3) 290 – 140 = 150 kilometers – the distance that the second motor ship sailed in 5 hours;
4) 150: 5 = 30 kilometers per hour – the speed of the second motor ship.
Answer: 30 kilometers per hour.
