Answer:
133.06 miles per hour
Step-by-step explanation:
Distance =2438.9 miles
Time=18 hours 20 minutes.
First we convert the time to hour
60 minutes = 1 hour
20 minutes=(20/60) hour=0.33
Therefore her time=18+0.33 hour=18.33hour
We are to determine the average speed of her flight in miles per hour.
rate=distance/time
=2438.9/18.33
=133.06 miles per hour
Her average speed is 133.06 miles per hour
Answer:
c = 85 in is the answer.
Step-by-step explanation:
a = 36 in
b = 77 in
c = ?
According to the Pythagoras theorem,
a² + b² = c²
36² + 77² = c²
1296 + 5929 = c²
7225 = c²
c = 85 in
∴ c = 85 in is the length of the missing leg.
