Tristan swam around a lake 8 times. the distance around the lake was 0.25 miles. he swam at an average of 60 minutes per mile. which explanation correctly tells how to calculate the time it will take tristan to complete his swim? a. step 1: figure out the total number of miles tristan swam (8 × 0.25). step 2: divide that distance into his average speed (60 ÷ 2). b. step 1: figure out the total number of miles tristan swam (8 ÷ 0.25). step 2: multiply that distance by his average speed (32 × 60). c. step 1: figure out the total number of miles tristan swam (8 ÷ 0.25). step 2: divide that distance by his average speed (32 ÷ 60). d. step 1: figure out the total number of miles tristan swam (8 × 0.25). step 2: multiply that distance by his average speed (2 × 60).

The answer is D. Multiply the number of times Tristan swam around the lake by the distance to get the total distance that Tristan swam. If he swam 1/4 a mile 8 times, then he swam 2 miles. Since it takes Tristan an hour to finish one mile and he swam 2 miles, you need to multiple 60 minutes by 2 to get the time Tristan took to swim. I hope that this was helpful and if so please leave a good rating and thanks and maybe even Brainliest answer. Thank you and have a good day!

The rate of change: 1/5

Initial value: (0,-1)

Step-by-step explanation:

The rate of change is easily 5/25, we just have to simplify it to 1/5.

To get the intial value, just subtract (2,9) by the rate of change twice.
