If Maya can run 18 miles in 3 hours, and she can bike 18 miles in 2 hours. And Maya biked for 3 hours and then ran for 1 hour and 30 minutes then her average speed is 8 miles per hour .
What is average speed?
Average speed is ratio of total distance and total time.
Here given that Maya can run 18 miles in 3 hours, and she can bike 18 miles in 2 hours. And Maya biked for 3 hours and then ran for 1 hour and 30 minutes.
Distance covered by maya by bike can be calculated as
[tex]\frac{18}{2} \times3\\\\9\times3\\\\27[/tex]
Distance covered by maya while running can be calculated as
[tex]d= \frac{18}{3} \times 1.5\\\\6\times1.5\\\\= 9\\[/tex]
So total distance can be calculated as
Total distance = 27+9= 36
And total time = 3+1.5=4.5 hour
Hence Average speed can be calculated as
[tex]\\\text{Average speed}= \frac{36}{4.5} \\\\=\frac{360}{45} \\\\= 8 \text{ miles per hour}[/tex]
