Cars speeds

Distance from city A to city B is 108 km. Two cars were simultaneously started from both places. The speed of a car coming from city A was 2 km/h higher than the second car. What was the speed of each car if they met in 54 minutes?

Result

a =  61 km/h
b =  59 km/h

Solution:


a=2+b
108 = 54/60*(a+b)

a-b = 2
-54a-54b = -6480

a = 61
b = 59
