Answer:
After 6 days Martha biked 330 miles, while Enrico biked 290 miles.
Step-by-step explanation:
i. Martha bikes 55 miles per day.
So that after 6 days, Martha would have covered;
55 miles x 6 = 330 miles
After 6 days, Martha would have biked 330 miles.
ii. Enrico bikes 145 miles every 3 days.
Then after 6 days, Enrico would have covered;
x 145 miles
= 2 x 145 miles
= 290 miles
After 6 days, Enrico would have biked 290 miles.
After 6 days Martha biked 330 miles, while Enrico biked 290 miles.
