Answer
$3728.372$ miles
Work Step by Step
The question gives you the expression $2193.16t$ for the total distance flown by the jet, in which $t$ is a variable for the number of hours.
The value for $t$ is given in the question, as $t=1.7$ hours.
Substitute this value back into the expression given and solve!
$2193.16t$
= $2193.16$ x ($1.7$)
= $3728.372$ miles
Remember to include the unit, in this question we are calculating the distance which will be in miles as the speed for the jet given was in miles per hour.
