Answer:
14/45
Step-by-step explanation:
Quotient is fraction
P/(2/5) = 7/9
P = 7/9 × 2/5
P = 14/45
Answer:
A
Step-by-step explanation:
3/4 times 24 is 18-4 is 14 and then you must do 1/2 times 24 which is 12 and then subtract by 10 which is 2
Answer:
The speed of the truck is 42 mph
Step-by-step explanation:
we know that
The speed is equal to divide the distance by the time
Let
s -----> the speed in miles per hour
d ----> the distance in miles
t ----> the time in hours
![s=\frac{d}{t}](https://tex.z-dn.net/?f=s%3D%5Cfrac%7Bd%7D%7Bt%7D)
![d=s(t)](https://tex.z-dn.net/?f=d%3Ds%28t%29)
step 1
Find out the distance traveled by the car at 7:00 P.M
we have
![s=46\ \frac{mi}{h}](https://tex.z-dn.net/?f=s%3D46%5C%20%5Cfrac%7Bmi%7D%7Bh%7D)
![t=7:00 P.M-4:00 P.M=3\ h](https://tex.z-dn.net/?f=t%3D7%3A00%20P.M-4%3A00%20P.M%3D3%5C%20h)
![d=s(t)](https://tex.z-dn.net/?f=d%3Ds%28t%29)
substitute the values
![d=46(3)=138\ mi](https://tex.z-dn.net/?f=d%3D46%283%29%3D138%5C%20mi)
step 2
Find out the speed of the truck
we know that
At 7:00 P.M the distance is equal to
![d=264-138=126\ mi](https://tex.z-dn.net/?f=d%3D264-138%3D126%5C%20mi)
![t=7:00 P.M-4:00 P.M=3\ h](https://tex.z-dn.net/?f=t%3D7%3A00%20P.M-4%3A00%20P.M%3D3%5C%20h)
substitute
![s=\frac{126}{3}](https://tex.z-dn.net/?f=s%3D%5Cfrac%7B126%7D%7B3%7D)
![s=42\ \frac{mi}{h}](https://tex.z-dn.net/?f=s%3D42%5C%20%5Cfrac%7Bmi%7D%7Bh%7D)
Last one for sure, the others im not too sure about
