Calculate 9571

At 9:00 AM, a car left Zlín in the direction of Brno, 98 km away. At 9:15 AM, a vehicle left Brno in the direction of Zlín and drove at a speed 6 km/h higher than the speed of the car traveling from Zlín. The cars met at 9:45 AM. Calculate the speeds of both cars.

Correct answer:

z =  76 km/h
b =  82 km/h

Step-by-step explanation:


z·(9+45/60-9.00)+b·(9+45/60-(9+15/60))=98
b = z+6

30b+45z = 5880
b-z = 6

Row 2 - 1/30 · Row 1 → Row 2
30b+45z = 5880
-2.5z = -190


z = -190/-2.5 = 76
b = 5880-45z/30 = 5880-45 · 76/30 = 82

b = 82
z = 76

Our linear equations calculator calculates it.
b=82=82 km/h
