Sure, let’s break this down into two separate parts, considering each question one by one.
### Part 1: Time Taken to Skate the Entire Length of a 12-Mile Bike Path
1. Determine Bradley’s speed:
Bradley skates 4 miles in 20 minutes.
[tex]\[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} = \frac{4 \text{ miles}}{20 \text{ minutes}} = 0.2 \text{ miles per minute} \][/tex]
2. Calculate the time to skate 12 miles:
We now need to find out how long it will take Bradley to skate the entire 12-mile bike path at his current speed.
[tex]\[ \text{Time} = \frac{\text{Distance}}{\text{Speed}} = \frac{12 \text{ miles}}{0.2 \text{ miles per minute}} = 60 \text{ minutes} \][/tex]
So, it would take Bradley 60 minutes to skate the entire length of the 12-mile bike path.
### Part 2: Cost to Buy Sweatshirts for a Team of 15 Players
1. Determine the cost per sweatshirt:
The cost of 5 sweatshirts is [tex]$90. \[ \text{Cost per sweatshirt} = \frac{\text{Total cost for 5 sweatshirts}}{\text{Number of sweatshirts}} = \frac{\$[/tex]90}{5} = \[tex]$18 \text{ per sweatshirt} \] 2. Calculate the total cost for 15 sweatshirts: If the team consists of 15 players, and each player needs one sweatshirt, then we multiply the cost per sweatshirt by the number of players. \[ \text{Total cost} = \text{Number of players} \times \text{Cost per sweatshirt} = 15 \times \$[/tex]18 = \[tex]$270 \] So, the total cost to buy sweatshirts for a whole team of 15 players would be $[/tex]270.
### Summary:
1. It would take Bradley 60 minutes to skate the entire length of the 12-mile bike path.
2. The cost to buy sweatshirts for a team of 15 players would be $270.
