#75# miles result in the same cost.

Explanation:

Given -
EZ car rental
Rental charge #=$.40#
Charge per mile #=$0.25#

ACE car rental
Rental charge #=$.25#
Charge per mile #=$0.45#

Let us assume #x# miles result in the same cost.

Then -

#40+0.25x=25+0.45x#
#0.25x-0.45x=25-40#
#-0.20x=-15#
#x=(-15)/(-0.20)=75 #miles
