The increase in temperature of the water is
The total mass of the water is the product between its volume and its density
And so we can find the amount of heat released by the pebble to the water, because this is equal to the amount of heat absorbed by the water, which is
The troposphere is the layer of the atmosphere which contacts the surface of the Earth. This layer is <span>0 to 12 km (0 to 7 miles).

Answer:
<em>The tourist's average speed was 80 mph</em>
Explanation:
<u>Average Speed
</u>
If an object travels a distance d in a time t regardless of the direction, the average speed is the quotient of the distance over the time:
The tourist leaves Pittsburgh and travels 60 miles South in 45 minutes. Then he heads West and travels 100 miles in 1 hour and 15 minutes.
The total distance traveled is:
d = 60 miles + 100 miles = 160 miles
The total time is:
t = 45 minutes + 1 hour + 15 minutes = 2 hours
The average speed is:
v = 80 mph
The tourist's average speed was 80 mph
