Given: Jacob and Issac decided to run to the basketball court
Distance between basketball court and school = 
miles
miles
Speed = 
miles per hour
miles per hour
Since, time = (distance) ÷ ( speed)
Now, the time taken by boys to arrive at the basketball court = 
hours
Hence, the required length of time =
Let us assume the common ratio to be = x
Then
(1 * x) + (4 * x) = 50
x + 4x = 50
5x = 50
x = 50/5
= 10
So from the above deduction, we get the common ratio to be equal to 10
Then
The smallest number = 1 * x
= 1 * 10
= 10
Answer: x = 2

Answer: the percentage of the original cost will the customer pay is 86.5%
Step-by-step explanation:
Let x represent the original cost.
During a christmas sales event the dealership offers a 13.5% discount off of the retail price. This means that 13.5% was offered off x. The amount that the customer will pay is
x - (13.5/100 × x) = x - 0.135x = 0.865x
The percentage of the original cost that the customer will pay will be determined by dividing the new amount by the original cost and multiplying it by 100. It becomes.
0.865x/x × 100 = 0.865 ×100
= 86.5%
