Final answer:
Clark swam a total of 1.7 miles when the distances of 8/10 of a mile and 9/10 of a mile are added together in decimal form.
Step-by-step explanation:
The student wants to know the total swimming distance covered on Monday and Tuesday in decimal form. To calculate this, we first convert the fractions to decimals.
The fraction 8/10 is equivalent to 0.8 miles, and the fraction 9/10 is equivalent to 0.9 miles.
To find the total distance, we simply add the two distances together:
0.8 miles (Monday) + 0.9 miles (Tuesday) = 1.7 miles
Therefore, Clark swam a total of 1.7 miles on both days.
