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:
2/7
Step-by-step explanation:
this is because you can simply do the butterfly method and multiply 4 times 2 which is 8 for 2/7 and 7 times 1 for 1/4 which is 7 so 2/7 is greater than 1/4

<h2>
Step-by-step explanation:</h2>
In this problem, we need to find the value of the given expression for which we need to simplify the given expression.

We need to solve the numbers within the parentheses.

We can bring the constant one side and variables another side.

Taking fourth root for ‘8’ and ‘3’ will give numbers which are very tough to solve further.
Since, we cannot solve the above equation further. The value of the given equation remains,
