Answer:
53.2 mph
Step-by-step explanation:
Mara's family travels 239.4 miles between the hours of 9:10 a.m. to 1:40 p.m. 
1:40 p.m. is 13:40.
Thus, they traveled for
13 hours 40 minutes - 9 hours 10 minutes = 4 hours 30 minutes 
that is  hours.
 hours.
Use formula:

where 
D = distance
r = rate
t = time.
In your case,
D = 239.4 miles
t = 4.5 hours
Hence,

P(B) = 0.75.
For independent events, P(A and B) = P(A)*P(B).  This gives us
1/8 = 1/6(x)
Divide both sides by 1/6:
1/8 ÷ 1/6 = x
1/8 × 6/1 = x
6/8 = x
3/4 = x
0.75 = x
        
             
        
        
        
Step-by-step explanation:
10% more = 110% of the number.
110% of the number = 132
100% of the number = 132 * (10/11) = 120.
The number is 120.
