Answer:
7.83 km/h
Step-by-step explanation:
At her constant pace, Nina's time for 6 km will be found by the proportion ...
(time for 6 km)/(6 km) = (time for 9 km)/(9 km)
time for 6 km = (6 km)/(9 km) × (75 min) = 50 min
Jo's time for the same distance will be 4 minutes less: 50 -4 = 46 min. Jo's speed is ...
speed = distance/time
= (6 km)/(46/60 h) = 360/46 h ≈ 7.83 km/h . . . . Jo's speed
_____
<em>Additional comment</em>
From the 6 km point, the remaining race is half the distance already run, so will take half the time already taken. As we know, Nina will finish in 25 more minutes; Jo will finish in 46/2 = 23 more minutes, 2 minutes ahead of Nina.

Answer:
0,24 m
Step-by-step explanation:
La table est un rectanble donc l'angle en haut à droite est de 90°.
Tu connais donc un angle et le côté opposé à l'angle et tu cherche le côté adjacent.
On sait que tan(â) = 
donc :
tan(40)= 
donc x ≈ 1,51 m
Le trou du mileu est à 
soit 1,27m du bord.
Donc elle doit taper à 1,51 - 1,27 = 0,24m du trou du milieu.
j'espère avoir été clair.
