Answer:
17.74Km/h
Step-by-step explanation:

I believe but I am not too sure.
Answer:
The rate of change is the slope
In this case
m=2d+50 is a slope intercept equation.
where m is where the y would be
the 2 which is originally where the slope or (m) would be
the d for the (x)
and 50 for the y intercpet or (b)
so
#1=2
The expalantion is the same but different numbers, when asked for the rate of change look at the slope or the number next to the variable. Also put it in y=mx+b form to make sure the number is correct.
#2= -6
The answer would be 92 over 63(92/63) since the least common denominator is 63
