Just gonna grab some points by answering this. Have a good day!
The speed during the first hour is the slope of the piece of line that shows the first hour on the graph.
Average speed is always=(distance covered)/(time to cover the distance)
Distance covered during the first hour = from 0 miles to 40 miles on the graph; that's 40 miles.
Time to cover the distance = from 0 hours to 1 hour on the graph; that's 1 hour
Average speed = (40 miles) / (1 hour)
Average speed during the first hour = 40 miles/hour
I love you too.

Explanation:
Answer: 510 m/s
Explanation: specific gravity of steam is 18/29 = 0.620
It is the ratio of the density of steam over density of water
400m3/s of steam =
400m3ms * 0.620 of water
= 248m3/s of water
Total flow rate Q = 248 + 7 = 255m3/s
Using Q = AV
Where A is area and V is velocity
V = Q/A
V = 255/0.5 = 510m/s
Liquid to a gas hence the name water vapor
