If we set the unknown distance (in miles) as x, then we set up an equation according to the data, we can solve for x.
Time taken to go to resort : x/48
Time taken to return : x/40
Total time = x/48+x/40 = 11
Solve for x
common multiple between 48 and 40 = 240
so
5x/240 + 6x/240 = 11
(5x+6x)/240 = 11
11x = 11*240, => x=240
Distance from home to resort is 240 miles
Answer:
12x < 4
Step-by-step explanation:
6x < 2 is twice 3x < 1
so 12x < 4 is twice 6x < 2
Answer:
a = 0.25
r = 4
n = 5
Step-by-step explanation:
Given series is,
0.25 + 1 + 4 + 16 + 64
Ratio of 2nd and 1st term = 
= 4
Ratio of 3rd and 2nd terms = 
= 4
There is a common ratio 'r' = 4
First term of the given geometric series 'a₁' = 0.25
n = Number of terms in the series
n = 5
