Answer
The top speed of the Indy car is 235 mph..
The top speed of NHRA car is 330 mph.
Work Step by Step
Let $i$ be the top speed of the Indy car.
The top speed of NHRA car is $i+95$.
$i+(i+95)=565$ $\longrightarrow$combine like terms
$2i+95=565$ $\longrightarrow$addition property
$2i+95-95=565-95$ $\longrightarrow$simplify
$2i=470$ $\longrightarrow$multiplication property
$2i\div2=470\div2$ $\longrightarrow$simplify
$i=235$
$i+95=235+95=330$
