Sam and Liam raced each other up and then down the hill. Sam's average speed up the hill was 1 mph, and his average speed down w
Furkat [3]

Answer:

Sam's time was 1 hour and 6.66 minutes (or 1 and 1/9 hours)

Liam's time was was 1 hour

So in conclusion, Liam was faster

Step-by-step explanation:

We got Sam's time by 1/1 because Sam was walking 1 mph and the length to reach the top of the hill is 1 mile. So it would take Sam 1 hour to walk 1 mile. Walking down the hill Sam's speed was 9 mph. So the equation would be 1/9. So you would get 1/9. 1/9 of 60 is 6.66 repeating.

For Liam it is pretty simple. Since he is going up the hill at 2 mph and the length of the bottom of the hill to the top is 1 mile, it would be 30 minutes. Repeat this for the top to the bottom and in total it would be 1 hour.

Hope this helps

In triangle PQR, p equals what.
Darina [25.2K]
The correct answer is 3.

The formula for the law of sines is the following:

P/sin P = Q/sin Q = R/sin R

So, if you break these up into two different equations, you will have: 

P/sin P = Q/sin Q and P/sin P = R/sin R

To solve, get P alone on one side of the equation by multiplying the other side by sin P:

P = Q sin P/sin Q and P = R sin P/sin R

When you look at the answers, you'll see that the second equation is an option.
