Answer:
4778.69 +d-z+b
Step-by-step explanation:
Initial balance of the joint checking account = $6238.67
Deposits in a month gets added in the account = d dollars
Maintenance fee is deducted in the account = z dollars
Interest on the account is added in the account balance = b dollars
Checks written also gets deducted form the account = $1459.98
Algebraic expression so formed is
6238.67 + d -z+b-1459.98
4778.69 +d-z+b
By definition we have to:
v = d / t
Where,
v: speed
d: distance
t: time
The time in hours is given by:
t = 4 + (45/60)
t = 4.75 hours
Substituting values we have:
v = 456 / 4.75
v = 96 km / h
Answer:
the speed of the train is:
v = 96 km / h
