To find: The relation between rates of swimming by Mr. M in two different days Monday and Tuesday.

Answer to Problem 31STP
Option B is correct answer as his rate of driving on Tuesday was 2 miles per hour less than her rate on Monday.
Explanation of Solution
Given information: Mr. M drove 340 miles in 5 hours on Monday and 198 miles in 3 hours on Tuesday.
Formula/Concept used:To calculate the rate of driving i.e. total distance covered in one hour on both days, following formula is used:
Rate of driving
And then each such rate will be compared with given statements.
Calculation: Rate of driving on Monday
Rate of driving on Tuesday
Conclusion: Based on above calculation,it is cleared rate of driving on Tuesday was 2 miles per hour less than the driving rate on Monday.
