15+10
i believe this is right
For this problem, I'd use cross-multiplication.
9/12 = x/8.
When cross multiplying, multiply 12*x and 9*8. This leads to a new equation:
12x = 72.
Then you solve as an algebra problem.
*Divide 12 on both sides*
x = 6.
Answer:
the time taken is 4 hours
Step-by-step explanation:
The computation of the time is shown below:
As we know that
Speed = Distance ÷ Time
50 miles per hour = 200 miles ÷ Time
So the time would be
= 200 ÷ 50
= 4 hours
Hence, the time taken is 4 hours
