Answer:
9.9 gallons
Step-by-step explanation:
To solve this problem, we need to cross multiply. Lets input the values (250, 275, 9) as shown below:
Next we cross multiply. We multiply 250 and x, and we multiply 9 and 275.
Now, lets put the values above back into the equation:
Lets solve this equation. First we divide 2,475 by 250, making x by itself.
This means that to drive 275 miles, Kala would need to use 9.9 gallons of gas.
0.0181 yd/s. To solve this problem you use dimensional analysis. You convert the feet and minutes to yards and seconds by using this process. The units of feet and minutes cancel out, so you are left with yards per second. You should get 0.0180555555 when you multiply and divide everything, but you can just round it to 0.0181 or whatever place your teacher wants.
