Celeste hiked 1.8 miles in 0.75 hour.
A. What is her average rate of speed?
B. Celeste estimates that she will finish her entire 6-mile trip in less than 2 hours. If she keeps hiking at the same average speed, is her estimate reasonable? Explain.

A) Average rate of speed = 2.4miles/hr

B) If Celeste keeps hiking at the average speed, she will cover 6miles in 2.5 hours.

This implies that her estimates to cover 6miles in less than 2 hours is not reasonable.

Step-by-step explanation:

Average rate of speed = Distance/Time

= 1.8/0.75 = 2.4miles/hr

If 1.8 miles = 0.75hour, find the time it will take to complete 6 miles, let the time be represented by x

6 miles = x

Therefore, 1.8 miles = 0.75hour

6 miles = x

We cross multiply

1.8x = 4.5

Divide both sides by 1.8

x = 4.5/ 1.8

x = 2.5hours

f Celeste keeps hiking at the average speed, she will cover 6miles in 2.5 hours.

This implies that her estimates to cover 6miles in less than 2 hours is not reasonable.
