let sonia has the (x)
Sandeep would have twice as much as Sonia so (2x)
together they'd have 150. 
so, x+2x=150
solve for X
3x=150 
X=150/3
So x=50 is what Sonia has, 
and Sandeep would have 2(50) =100
 
        
             
        
        
        
In this question, we're trying to find how many miles a car travels in 15 minutes.
We know that the car travels at 85 mph.
However, we need to know how many miles it travels per minute.
To find this, we would divide 85 by 60.
85 ÷ 60 = 1.4166
The car drives at a speed of about 1.42 per minute.
We need to know how far it goes in 15 minutes, so multiply 1.42 by 15.
1.42 · 15 = 21.3
The car travels at a approximately 21.3 miles in 15 minutes.
