angela made the trip by bus in 16 hours and the return by car in 20 hourse.
the bus traveled 10 miles per hour faster than the car. how far was the trip ?
D = Rate x Time DCAR = R mi/hr • 20 hr DBUS = (R+10 mi/hr) • 16 hr
The distance is the same both times. DCAR = DBUS
20R = 16R + 160
4R = 160
R = 40 mph
DCAR = 40 mph • 20 hr = 800 mi
check answer
Does DBUS = 800 mi ?
(40+10 mph) • 16 hr = 800 mi ?
50 mph • 16 hr = 800 mi ?
800 mi = 800 mi True
