On Monday, Barb drove to town at 40 miles per hour. On Tuesday, she drove to town at 30 miles per hour. If the total travel time for both trips was 7 hours, how far was it to town?

Step-by-step explanation:

He traveled at 60 mph a distance of 60*hours.

He traveled at 40 mph the same distance of 40(15 hrs - time hrs). The distance is the same; therefore, set them equal.

60t = 40(15-t)

60t = 600 - 40t

100t = 600

t = 6 hrs for the 60 mph day.

15-t = 9 hours for the 40 mph day.

distance = 6 h x 60 mph = 360 miles.

distance = 9 h x 40 mph = 360 miles.
