Abicyclist started riding at 8: 00 a.m. the diagram below shows the distance the bicyclist had traveled at different times. what was the bicyclist's average rate of speed in miles per hour? 8: 00 a.m. --> 3.5 > 8: 14 a.m. > 8.5 > 8: 48 a.m. the average rate of speed is miles per hour.

I think that it is saying that 8:15-8:45 is 7.5 miles right? Then 8- 8:15 is 4.5 and you are trying to find the average of an HOUR. So in order to get an hour you need 15 more mins. Which is 4.5 miles according to the chart. (8-8:15). So 4.5+4.5+7.5=16.5. Divided by three is 5.5 miles per hour. I'm not sure but this is what I would do.

Average rate of speed is equal to total distance divided by the total time. the total distance is equal to 4.5+7.5, or 12 miles. The total time from 8:00 to 8:48 is 48/60 of one hour. 12*60/48=15 miles per hour

Answer : The bicyclist's average rate of speed in miles per hour is 15 mile/hr.

Step-by-step explanation:

Average rate if speed : It is defined as the ratio total distance to total time.

Formula used :

As per question,

Total distance traveled by bicyclist = 4.5 mile + 7.5 mile = 12 mile

Total time taken by bicyclist = (8:48 A.M - 8:00 A.M) = 48 min = 0.8 hr

conversion used : ( 1 hour = 60 minute)

Now put all the given values in the above formula, we get the bicyclist's average rate of speed in miles per hour.

Therefore, the bicyclist's average rate of speed in miles per hour is 15 mile/hr.

True.

Step-by-step explanation:

Linear measurement : It is defined as the measurement of length.It also measure thickness, height and diameter. It is  can be measured in meter, inches, centimeter, feet etc.

We are given that

Therefore, height of  triangle =x, base of triangle= 12 units

We change 15 seconds  into minutes

1  minute =60 seconds

Now add 34' to minutes then we get

Now , we changing minutes into degree

1 degree= 60 minutes

Therefore ,

By cross multiply

Height =x=0.1195 units

It is linear measurement.

Therefore, it is true.
