Distance 8591

The distance between A and B is 132 km. At 9:00, a cyclist set off from A at 24 km / h. At 10:00, a cyclist set off from B at a speed of 30 km / h. How long and for how long will they meet (from A)?

Correct answer:

t =  2 h
a =  72 km

Step-by-step explanation:

a+b = 132
24(t+1) = a
30t = b

a+b = 132
24•(t+1) = a
30•t = b

a+b = 132
a-24t = 24
b-30t = 0

a = 72
b = 60
t = 2

Our linear equations calculator calculates it.
a=72=72 km
