It says Sandeep has twice as much as Sonia. Thus, let Sandeep's amount be 2x and Sonia's amount be x.
Now, together they have 150.
Thus, the equation;
x+2x=150
Now let's solve the equation;
3x=150
x=150/3
x=50
Thus, Sonia has 50
multiplication is for example 10×500=5,000
division is for example 5,000÷10=500
Answer:
0.333...
Step-by-step explanation:
6×8=48
48÷9=5.333...
(The ... means repeating)
It can be easily assumed that most information's are already given in the question. Based on those information's, the answer can be deduced.
rt = [(3/4)r] * (t + 12)
4rt = 3r (t + 12)
4rt = 3rt + 36r
4rt - 3rt = 36r
rt = 36r
t = 36
From the above deduction we can conclude that the time taken by Carmen to ride to the market is 36 minutes
Then
Time taken by Carmen to ride home = 36 + 12 = 48 minutes
