We need to find the time taken to travel from Frederick, MD to Baltimore, MD at a speed of 15 miles per hour.

The time taken to travel the distance is 3 hours and 20 minutes.

The shortest route from Frederick to Baltimore is 50.2 miles via the I-70 E.

So we can assume this route will be taken.

Speed of the cyclist = 15 mph

Time is given by distance divided by speed.

So,

t=\dfrac{50.2}{15}\\\Rightarrow t=3.34\ \text{hours}

Converting to hours and minutes

0.34\times 60=20.4\approx 20

The time taken by the cyclist would be about 3 hours and 20 minutes.
