You would have to use an equation. The equation should be 12n+16n=1.5
When you found your answer, you should then use that decimal amount to "times" one hour to get the time. I am pretty sure that this is correct.
Average speed = total distance divided by total time.
In the first part, the car covered 490 km in 7 hours, but I think you mistyped the second part (“then covers a speed of 90km”) and a critical piece is missing to find the total distance and time.
Answer:
480 miles
Step-by-step explanation:
*please stop titling your questions as: “Help help help help help help help help help help help plsss” thank you*
120/1.5 = 80
80 x 6 = 480
It can travel 480 miles in 6 hrs.
Answer:
It would be - 72
Step-by-step explanation:
It is because assume the integer as 'a'.
Given, a/9 = -8
That is a = -8 * 9 => -72
Hey there!! So first you gotta get a calculator and put in the check Mark thingy and 96 which would be 9.79795897113271 then you multip by 10 which is just 97.9795897113271 but your teacher would probably want it to the nearest tenth so we would say 98. I’m probably wrong but I hope this helps!!
