In a movie script, a man was desperate to change

the past,

which led him to invent a working time

machine that would let him

go back in time. He wanted

to avoid the death of his wife who died during

the same year. The couple were of the same age

. However, he may have gone t

oo far as his age was

now three times

the age

of his wife.

If he went back 20 years in the past, how old

is our time traveler?
