Difference 7985

The distance between cities A and B is 125 km. Two cars start from these places at the same time. The difference in their speed was 3 km/h. They met in an hour. What was the speed of each car?

Correct answer:

v1 =  64 km/h
v2 =  61 km/h

Step-by-step explanation:

v1 = 3+v2

v1+v2 = 125
v1-v2 = 3

Row 2 - Row 1 → Row 2
v1+v2 = 125
-2v2 = -122

v2 = -122/-2 = 61
v1 = 125-v2 = 125-61 = 64

v1 = 64
v2 = 61

Our linear equations calculator calculates it.
v2=61=61 km/h
