On Monday, Roger drove to work in 38 minutes.
On Tuesday, he averaged 10 miles per hour more, and it took him 5 minutes less to get to work.
How far (in miles) does he travel to work?
:
Find his speed first
:
The dist is the same each day, write a distance equation dist = time * speed
we have to change the minutes to hours
:
s = *(s+10)
multiply both sides by 60
38s = 33(s + 10)
38s - 33s = 330
5s = 330
s = 330/5
s = 66 mph on Monday
and
76 mph on Tuesday
:
Find the distance
(66) = 41.8 miles
check that the distance is the same on Tuesday
(76) = 41.8 miles
