Answer:
In 1.25 hours, their combined speed is 40 km, so their speed per hour is 32 km/h
So the answer is B. northbound bicyclist = 18 km/h
southbound bicyclist = 14 km/h
Step-by-step explanation:
the speed of the slower is x and the faster x+4 km/h
that equals 32 km and the speed of the slower is 14 km/hr and the faster 18 km/hr.
in 1h15m the slower goes 17.5 km and the faster 22.5 km
Y=180-69=111
4x+7=y
4x+7=111
4x=111-7
4x=104
X=26
Answer: x=26, y=111
Answer:
9
Step-by-step explanation:
14/y=112/72
simplify 112/72 into 14/9
14/y=14/9
y=9
786,432 just multiply 768 times 1,024
Answer:
Arithmetic sequence
Step-by-step explanation:
A sequence is described as an arithmetic sequence when there is a common difference between the numbers
A sequence is a geometric sequence when there is a common ratio between the numbers
12,10,8
10-12= -2
8-10= -2
10/12= 0.83
8/10= 0.8
Hence the sequence is an arithmetic sequence with a common difference of -2
