(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

was a home work problem. im redoing it for practice

im stuck on part c

this is the hint for part C

2. Relevant equations

t=T/(1-(v/c)^{2})^{1/2}

3. The attempt at a solution

my attempt.

i know that from the restaurant to school it will take 15 min in school's frame and ice cream melts in 5min in the car riders frame..so i did

(15/60)=(5/60)*(1-(v/c)^{2})^{-1/2}

so i solved for v and got c=37.74. which was wrong, do not know where im going wrong.
