the answer is A. m=7t     You get your answer by dividing 7 into m
m=10.5 miles    10.5 divided by 7 equals 1.5    time is 1.5 hours

Answer:
98 
Step-by-step explanation:
 
        
             
        
        
        
3x^(2)+4x-3x-5-2=0
3x^(2)+x-7=0
Discriminat= b^(2)-4ac= 1^(2)-4(3)(-7)= 1-12(-7)=1+84=85
The discrimination is bigger than 0 (delta>0) therefore there are 2 real solutions
