## Homework Statement

Velma and Mort have identical 10-minute melting ice-cream cones. How fast must Velma move in order for her 10-minute cone to last 3 times longer than Mort’s, as measured by Mort?

## The Attempt at a Solution

[/B]

We have not gotten too in depth into mathematics in my class as it mainly focuses on conceptual understanding and estimates. I looked at a table in my textbook and it says that at 0.9

*c*there is a time dilation of 2.3 and then it jumps to say that at 0.99

*c*the time dilation is 7.1 so if Mort observes Velma's ice-cream melt slower by a factor of 3...then shouldn't she be moving slightly faster than 0.9

*c*and slower than 0.99

*c*? Would that be a reasonable answer? or is there another way to determine the time dilation? Thanks!
