Answer:
57 miles per hour
Step-by-step explanation:
Speed is equal to distance over time
I changed the fractions to decimals for ease of math
distance = 370 .5 miles
time = 6.5 hours
Speed = 370.5/6.5 = 57 miles/hour
Solve for x by simplifying both sides of the equation, then isolating the variable.
x = 10
Answer:
No trees and just buildings.
