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).

Brennen · Answer 1

Total of 8 times

Distance is 0.25 miles

8 * 0.25 is 2 so a total distance of 2 miles

We know his avg swim rate to be 60 minutes per mile, meaning if he traveled 2 miles then we multiply it by 60 to get our total time taken.

60min/mile * 2 miles = 120 minutes total

So, step D is the same as what I've done to calculate the total time it will take Tristan to swim around the lake
