Answer: Time at which the meet = 10:17:24 am
Step-by-step explanation: Speed of Ivan = 12 mph
Speed of Kate = 16 mph
Total distance traveled = Initial separation = 40 miles
Ivan leaves his house at 8:00  a.m and Kate leaves her house at 9:30  a.m
If t is the time of catch up after Ivan starting, time taken by Kate is t - 1.5,
We have
             Distance = Speed x Time
          Total distance traveled = Distance traveled by Kate + Distance traveled by Ivan
        40 = t x 12 + (t-1.5) x 16
         40 = 28t - 24
          28t = 64
              t = 2.29 hours
So after 2.29 hours of Ivan's starting they meet,
Time = 8:00 am + 2.29 hours = 10:00 am + 0.29 x 60 minutes = 10:17am + 0.4 x 60 seconds = 10:17:24 am
Time at which the meet = 10:17:24 am
 
        
             
        
        
        
Answer:

Step-by-step explanation:

The first set of parentheses is unnecessary, so it can just be removed.

To remove the second set of parentheses, you must distribute the negative sign that is to its left. It changes every sign inside the parentheses.

Now you combine like terms.


 
        
             
        
        
        
b=16 , First you multiply 30 by 2 to see what sum you need for the numerator. Then you subtract the 60 that you get by the 12 and get 48. So 3 multiplied by b should give you 48. So you just divide 48 by 3 and get 16.
