Agroup of bike riders took a 4.0 hour trip. during the first 3.0 hours, they traveled a total of 50. kilometers, but during the last hour, they traveled only 10. kilometers. what was the group's average speed for the entire trip?

15 km/h

Step-by-step explanation:

Distance traveled in first 3 hours = 50 km

Distance traveled in last one hour = 10 km

Total time taken, t = 3 hours + 1 hour = 4 hours

Total distance traveled = 50 km + 10 km = 60 km

The average speed is defined as the ratio of total distance traveled to the total time taken.

Average speed = 15 km/h

Thus, the average speed of the bike riders for the entire trip is 15 km/h.

data plot with   3 dots over 33, 1 dot over 34, 2 dots over 35, no dot over 36, 1 dot over 37, 2 dots over 38, 4 dots over 39, and 2 dot over 40.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
