Pls help me Q) Sophia and Isabella are running on a circular path which is 400 meters long. Sophia’s speed is 10 kilometers per hour and Isabella’s speed is 11 kilometers per hour. They started at the same time from the same point of the track. In how many minutes will Isabella be one lap ahead of Sophia?
Explain too plzzz!

The answer would be c.hope this .

Okay so n is going to represent our first number. since the second number of five times greater than n, the second number will be represented as 5n. for us to figure out the two  numbers we need to have  the value of n first. this is going to be done by adding the two numbers together, n and 5n. it can be simplified as 6n, which the problem states is equal to 72. divide 72 by 6n and you can solve for n.  n+5n=726n=72n=(72/6)n=12  now that we know the value of n, we have to multiply 5 times 12 which equals 60. so our two numbers/integers are 12 and 60
