how many minutes does it take to travel 120 miles at 400 miles per hour?
.
You will be applying the "distance formula":
d = rt
where
d is distance
r is rate or speed
t is time
.
Let's start by solving:
d = rt
for 't':
t = d/r
.
Plugging in the given values:
t = 120/400
t = 3 hours
Since the problem wants the answer in terms of minutes:
t = 3 hours * 60 mins/hour = 180 minutes
