Answer:C
Step-by-step explanation:
If Jeff did not pass math he would definitely be not happy because he did not pass. Therefore if Jeff passes math he will be happy so that implies if he doesn’t pass math he is not happy
Answer:
a
if he passes he will be happy
n = 6
rate of the current = 2 mph
d = rt
Let c = rate of the current
Rate going downstream = c + 40
Time going downstream = 126/(40 + c)
Rate going up stream = 40 - c
Time going upstream = 114/(40 - c)
Since the times are equal, then
126/(40 + c) = 114/(40 - c)
126(40 - c) = 114(40 + c)
5040 - 126c = 4560 + 114c
240c = 480
c = 2 mph
This is not linear.
