Distance...3

Maria left home and traveled toward the capital at an average speed of 80 km/h. Some time later, Imani left traveling in the opposite direction with an average speed of 45 km/h. After Maria has traveled for six hours they were 705 km apart. Find the number of hours Imani traveled.

Let me see.

Maria:

rate = 80 km/h

time = x + 6

Imani:

rate = 45 km/h

time = x

Distance 705 km

80(x + 6) + 45x = 705

You say?

should be: 80*6 + 45x = 705

Maria left home and traveled toward the capital at an average speed of 80 km/h.
d=80*x
"After Maria has traveled for six hours", means x=6
d=80*6

Ok. Thanks for correcting my work.
