We know, speed = distance / time
Here, distance = 1000 Km
t = 7 5/6 = 47/6 hours
S = 1000 * 6 / 47
S = 6000 / 47
S = 127.65 Km/h
[ Please check your distance would be 100 Km i guess, if yes, then your answer will be B) 12 Km/hr ]
Hope this helps!
Huh? What are you saying?
First step is to find R
use The equation QR =43
R=43/Q
now since we have R plug that into PR= 9x - 31
P(43\Q) = 9x - 31
P43/QP +31 =9x
9x=P43÷QP +31
x=P43÷QP+31 /9
Since the question doesnt specify to leave the question in terms of P or Q i suppose this is the final answer
Hope this helps! xD
would not mind if you put it as the brainliest answer
