Jeremy rode his bicycle in a race. He averaged 15 mph and began the race 1 hour ahead of the other riders. The variable d represents Jeremy's distance ridden, in miles. The variable t represents the number of hours since the other riders began the race. Which equation can be used to determine the distance Jeremy rode t hours into the race? d = 15t + 1 d = 15(t + 1) d = 15(t - 1) d = 15t - 1

Travel Time The distance $d$ you bike varies directly with the amount of time t you bike. Suppose you bike $13.2 \mathrm{mi}$ in $1.25 \mathrm{h}$. What is an equation that relates $d$ and $t ?$ What is the graph of the equation?

The accompanying graph shows the total distance $s$ traveled by a bicyclist after $t$ hours. a. Estimate the bicyclist's average speed over the time intervals $[0,1],[1,2.5],$ and $[2.5,3.5] .$ b. Estimate the bicyclist's instantaneous speed at the times $t=\frac{1}{2}$ $t=2,$ and $t=3 .$ c. Estimate the bicyclist's maximum speed and the specific time at which it occurs.

00:01 This problem, it is said that a girl rides a bike at an average speed of 11 .5 miles per hour.
00:06 The distance that she rides can be represented by d of t is equal to 11 .5t, where t is the time in hours.
00:16 Now, first of all, we want to find d of 1.
00:18 So all we need to do is replace t by 1 in this expression over here.
00:24 So we end up with 11 .5 times 1, and that is equal to 11 .5...
