A and B teams of students set out from two places 18 kilometers apart at the same time and walk in opposite directions Team a travels 5 kilometers per hour and team B travels 4 kilometers per hour. When the two teams meet, how many kilometers do the cyclists travel?
When we met, we walked 18 (5 + 4) = 2 hours
Left and right 14 * 2 = 28 km
At 8:00 a.m., a and B are facing each other at the same time. At 10:00 a.m., they are 36 kilometers apart,
Two people continue to advance, to 12 o'clock and 36 kilometers apart, known a than B more than 2 kilometers per hour, to find a speed
If B is x kilometers per hour, then a is x + 2 kilometers per hour
(x+x+2)×(12-10)=36+36
2x+2=36
2x=34
x=17
17+2=19
A: the speed of a is 19 kilometers per hour, and that of B is 17 kilometers per hour
