Answer:
0.5hrs
Step-by-step explanation:
Let the speed downhill be 
,
Speed uphill is 
. We are told than speed uphill is 
the speed on flat ground. Therefore the speed on level ground will be 
.
From this info, we can obtain the actual speed,
on level ground as:
speed, distance and time have the relation 
so to obtain time to cover 45miles:
Hence it takes 0.5hrs to cover 45miles on flat ground.
This would be exponential growth
A= 500,000(1+.0625)^10
=500,000(1.0625)^10
=500,000* <span>1.83353577126
the population after 10 years= </span><span>916,767
A=500,000(1+.0625)^20
=500,000(1.0625)^20
=500,000* 3.36185342451
the population after 20 years would be= </span><span>1,680,926</span>
Answer:
36hr 16min
Step-by-step explanation:
1pool/17hr - 1pool/32hr = 1 pool/xhr
1/17 - 1/32 = 1/x
Use common denomminator of 17*32 = 544
32/544 - 17/544 = 1/x
15/544 = 1/x
x = 544/15
x = 36 4/15 hr
x = 36hr 16min
The answer is B) 20 lbs for $22 because carol is getting 8 pounds more for only $9+
82.4+108.6=191 and 12052.1 divided by 191=63.1
So the answer is 63.1
