Meteor Garden Problem :(

Homework Statement

Hi Guys.. I am really having a trouble in physics.. :( I really can' t solve uniform accelerated motion problems correctly. Can someone help me? please.. Our teacher gave this Meteor Problem. Help Please.

An unforgettable scene from “Meteor Garden”
San Chai was holding a bag of lemons when she saw Dao Ming Xi in a bus moving at a constant velocity of 1.5 m/s. She stood still mixed in an array of emotions. Then, as the bus was about 15 m away, she ran to catch up, accelerating at a rate of 0.40m/s2. If she continued to running and did not trip over, how long would it have took her to catch up?

Homework Equations

the four kinematic equation

The Attempt at a Solution

Forum rules state that you have to provide an attempt at a solution or at the very least try to describe exactly where the problem lies and why you can't continue from there. You haven't even put the effort into listing the equations.

You will need two equations one for the bus and one for San Chai. Which two equations do you think you will need and why? Write them out in formula form and explain the variables to me.
