Answer:
Step-by-step explanation:
She drives 1/2 hour at 50 km/h (from 8:00 - 8:30)
She then drives 1 hour at 40 km/h (from 8:30 - 9:30)
She reaches her destination, stops, and heads home at 10.
0.5 hours at 50 km/h = 25 km traveled
1 hour at 40 km/h = 40 km traveled
25+40 = 65 km (Total distance)
Returns at 60km/h, total 65km
65/60= 1.08 hr
~1:05 hr.
