50 secs
as $90÷5hrs= 18 $ per hrs
$18÷60min=$0.30 per min
$0.30÷60sec=$0.005 per sec
$0.25÷$0.005= 50sec to make $0.25
so 50sec is the answer
The coefficient of determination is 0.65.
According to the given question.
For a regression analysis,
SST = 120
and, SSE = 42
Since, coefficient of determination for a regression analysis = SSR/SST
So,
SSR = SST - SSE
⇒ SSR = 120 - 42
⇒ SSR = 78
Therefore, the coefficient of determination for the given regression analysis
= 78/120
= 0.65
Hence, the coefficient of determination is 0.65.

The 7 m/s is greater when he is running and he will pay the least amount of money at shop 1.
<h3>What is the percentage?</h3>
It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
We have:
When Ron cycles, his maximum speed is 20 km/h when Ron runs, his maximum is 7 m/s.
= 20 km/h = 20(1000)/(60×60) m/s
= 5.55 m/s
7 > 5.55
The greater is 7 m/s.
Shop 1
3.99 tube: buy 2 get 1 free
2 tube cost = 2×3.99 = 7.98
Each unit cost = 7.98/3 = 2.66
Shop 2
3.99 a tube with 20% off:
= 20% of 3.99
= (20×3.99)/100
= 0.798
The cost of 1 tube = 3.99 - 0.798 = 3.192
He will pay the least amount of money at shop 1
Thus, the 7 m/s is greater when he is running and he will pay the least amount of money at shop 1.
