Answer:37.2 sec
Step-by-step explanation:
Given
Joel takes 81 sec for 14 mile long track
speed of joel 
mi/min=10.37 mi/min
Jason takes 69 sec for 14 mi track
so jason speed is 
if both starts from same spot in opposite direction then
where x is distance covered by Joel
then x=6.44 miles
therefore time required
The radius of Earth is 6378.1 km,
which is 2981.1 km longer than the radius of Mars.
The radius of Mars is 3397 km.
Sport City is the better deal.
Sport City = 180 - (180 x .15) = $153
Tennis World = 200 - (200 x .20) = $160
Answer:
Step-by-step explanation:
3x - 4y = 9...........(1)
2x + 8y = 6..........(2)
Multiply (1) by 2 and (2) by 3
6x - 8y = 18.........(3)
6x + 24y = 18......(4)
Subtracting (3) from (4)
24y - (-8y) = 18 - 18
24y + 8y = 0
32y = 0
y = 0/32
y = 0
Substituting y = 0 into (1)
3y - 4y = 9
3y - 4(0) = 9
3y = 9
y = 9/3
y = 3
