Answer:
True
Step-by-step explanation:
180 is a whole revolution
The value of the variable y is 9 given that BDJ=7y+2 and angle JDR=2y+7
From the attached diagram, we can see that the<u> sum of m<BDJ and m<JDR is complementary</u> (i.e. sums up to 90degrees)
Given the following
m<BDJ = 7y + 2
m<JDR = 2y + 7
Summing up to 90
m<BDJ + m<JDR = 90
7y + 2 + 2y + 7 = 90
7y+2y+2+7 = 90
9y + 9 = 90
9y = 90-9
9y = 81
y = 81/9
y = 9
Hence the value of the variable y is 9

1 km = 1000 meters and 1 hour = 3600 seconds.
9x1000= 9000
9000/3600= 2.5
Your answer would be 2.5 meters per second.
