Answer: 58 in
Step-by-step explanation:
Let speed of car be x mph
At 1pm, cargo is 26 mph * 1 hour = 26 miles away from intersection.
At 1pm, car is x mph*30 minutes = x/2 miles from intersection.
Since it is given they travel in opposite directions, and are 51 miles apart, we have
26+x/2=51
Solve for x
x/2=51-26=25 mph
x=25*2=50 mph.
Car was travelling at 50 mph
15. It kind of seems as if there is an order going on here. So my guess is 15.
6 divided by 1=6
12 divided by 2=6
54 divided by 9=6
42 divided by 7=6
Answer:
When x=5, f(x)=0
Step-by-step explanation:
![f(x)=x-5\\\\f(5)=5-5\\\\f(5)=0](https://tex.z-dn.net/?f=f%28x%29%3Dx-5%5C%5C%5C%5Cf%285%29%3D5-5%5C%5C%5C%5Cf%285%29%3D0)
Therefore, when x=5, f(x)=0
