Final answer:
The highest possible score Bridget and Andrew can achieve is 56 points by performing 8 lifts, as each lift gives 7 points and fits into the two-minute routine without exceeding the 10 move limit.
Step-by-step explanation:
The goal is to find the highest possible score Bridget and Andrew could earn with the constraints given:
1. Their routine can last two minutes or less.
2. They can complete up to 10 moves in total.
3. Each spin takes 10 seconds to complete and is worth five points.
4. Each lift takes 15 seconds to complete and is worth seven points.
Given there is a two-minute (120 seconds) time limit and a maximum of 10 moves allowed, let's calculate the maximum possible number of each move without exceeding the time limit:
- The maximum number of spins would be 120 seconds / 10 seconds per spin = 12 spins (limited to 10 by the total number of moves).
- The maximum number of lifts would be 120 seconds / 15 seconds per lift = 8 lifts.
Since they have a stamina constraint to perform a maximum of 10 moves, we need to find the combination of spins and lifts that maximizes the score without exceeding 10 moves and the two-minute limit. To find this, we need to consider the points scored for each type of move:
- 5 points per spin.
- 7 points per lift.
Performing more lifts would give a higher score because each lift has a higher point value than each spin. However, we also need to consider the time it takes for each lift. The optimal strategy involves maximizing the number of lifts within the constraints:
- Perform 8 lifts, which takes 8 x 15 seconds = 120 seconds and yields 8 x 7 points = 56 points.
- As the routine is now at the two-minute limit, no additional moves can be added.
Therefore, the highest possible score they can achieve is 56 points by performing 8 lifts within the constraints of their routine.
