Abicyclist started riding at 8: 00 am. the diagram below shows the distance the bicyclist had traveled at different rates. what was the bicyclist's average rate of speed in miles per hour?

8: 00 am - 3.5 miles - 8: 14 am - 6.5 miles - 8: 40 am

the average rate of speed is miles per hour

The average rate of speed is 15 miles per hour

Explanation:

Given a bicyclist started riding at 8:00 am

Between 8:00 am and 8:14 am, that is, 14 minutes, he travelled 3.5 miles

And, between 8:14 am and 8:40 am, that is, 26 minutes, he travelled 6 miles

Total time = 14 + 26 = 40 minutes

=

Total distance travelled = 3.5 + 6.5 = 10 miles

Substituting the values,

Therefore, the average rate of speed is 15 miles per hour

d)  y = -2x + 17.

Step-by-step explanation:

Use the point-slope for  of the equation of a line:

y - y1 = m(x - x1)  where m = the slope and (x1, y1) is a point on the line.

So here we have:

y - 5 = -2(x - 6)

y = -2x + 12 + 5

y = -2x + 17.
