Question

It takes traci 12 minutes to get to school. It takes Antonio 3 more minutes to get to school than traci.. Antonio trip to school is 3 times as long as Frankle. How long does it takes Frankie to get to school?

Answer 1

It takes 5 minutes for Frankie to get to school.

Solution:

Given that Time taken by traci to get to school = 12 minutes

Also given that It takes Antonio 3 more minutes to get to school than traci.

So time taken by Antonio to get to school = Time taken by traci to get to school + 3

=> Time taken by Antonio to get to school = 12 + 3 = 15 minutes.

Also given that trip to school is 3 times as long as Frankie.

Means Antonio takes 3 times more time that Frankie.

Let assume time taken by Frankie = "x" minutes

=> Time taken by Antonio = 3 times of time taken by Frankie =
`3 * x = 3x`

But we have calculated earlier that time taken by Antonio = 15 minutes

=> 3x = 15 minutes

=>
`x = (15)/(3)=5 minutes.`

Hence it takes 5 minutes for Frankie to get to school.
