Answer:
g=6
Step-by-step explanation:
11 hours
Find how many hours the trip will take by dividing the number of miles by the rate in miles per hour:
660/60
= 11
So, the trip will take 11 hours
21.6 km/hr
multply the speed value by 3.6
b=2.6
b+2=4.6
Subtract both sides by 2 to isolate b
b+2-2=4.6-2
Therefore, b is equal to 2.6.
I hope this helps!
