Answer:
Her daughters age: 1/2x
Step-by-step explanation:
Let's say Rani's present age is x. Her age is twice the age of her daughter.
So if Rani's age is 20, her daughters age would be 10, because Rani is twice the age of 10; so 10 times 2 would be 20.
1/2(20)=daughter's age
so if you substitute x into 20 because we don't actually know Rani's age, it would be 1/2(x)=daughter's age.
hope this helped :-) <3
Start by converting 300 feet to miles and 2.92 seconds to hours.
300 feet 1 mile
----------- x -------------- = ?
1 5280 feet
2.92 sec 1 hr
----------------- * ---------------- = ?
1 3600 sec
Reduce each of the above fractions. Then convert 300 feet
-------------- to the
2.92 sec
equivalent speed / rate in mph using the converstion factors you derived earlier.
