Question 552504: how far would a car go in 8 hours if it runs 4.5 km/hr.?
Answer by lmeeks54(111)   (Show Source):
You can put this solution on YOUR website! This is pretty straightforward and requires understanding the relationships between distance (d), time (t), and rate (r).
...
The basic formula for distance, rate, and time is:
...
d = r * t
...
Given:
t = 8 hrs
r = 4.5 km/hr
...
Solve for d:
...
d = 4.5 km/hr * 8 hrs
d = 36 km (the hours cancel out)
...
Note: for other problems in this same series asking you to solve for r or t, rewrite the basic equation and solve for the missing quantity:
...
d = r * t
r = d / t
t = d / r
...
Cheers,
