Cross road

From the junction of two streets perpendicular to each other, two cyclists (each on another street) walked out. One ran 18 km/h and the second 24 km/h. How are they away from a) 6 minutes, b) 15 minutes?

Correct answer:

a =  3 km
b =  7.5 km

Step-by-step explanation:

v1=18 km/h v2=24 km/h  v=v12+v22=182+242=30 km/h t1=6 min h=6:60  h=0.1 h a=t1 v=0.1 30=3 km
t2=15 min h=15:60  h=0.25 h  b=t2 v=0.25 30=7.5 km
