Answer:
220 miles
Step-by-step explanation:
t = 6:30 - 2:30 = 4 hours
r = 55miles/hr
d = rt
d = 55miles/hr * 4hr
d = 220 miles
Total number of websites = 6
Number of school websites = 2
Number of social websites = 4
If she checks the social website first, the probability of checking a social website will be = 4/6
When one social website is checked, she is left with 3 social website and 2 school websites. So now the total number of websites is 5.
The probability that the second website she checks is school related = 2/5
The approximate probability that she checked a social website first, then a school-related website = 4/6 x 2/5 = 0.267
So option B gives the correct answer.
