Marcus needs to bike at least 11 miles each day.
Step-by-step explanation:
Given,
Distance to cover = 80 miles at least
Distance already biked = 25 miles
Number of days left = 5
Let,
x be the distance to cover in 5 days.

Answer:
8 loads can be expected to occur during a 4-year period
Step-by-step explanation:
This question can be solved by a simple rule of three.
Suppose the mean time between occurrences of loads is 0.5 year.
This means that for 0.5 years, 1 occurence is expected.
(a) How many loads can be expected to occur during a 4-year period
0.5 years - 1 occurence
4 years - x occurrences
8 loads can be expected to occur during a 4-year period
