11-108.

No calculator! The velocity of a train during a $90$ minute ride is given by $v = e^{2t} + 34$ miles per hour where $t$ is in hours. What is the average velocity during the trip?

$\$

The velocity of the train is given in mph, so use $1.5$ hours instead of $90$ minutes.

$\frac{1}{1.5}\int_0^{1.5}(e^{2t}+34)dt$
