Question 1087330: Rachel and Sarah started out to visit Grandma. They drove for 50kms and stopped to rest before driving for 30 more kilometers. They decided to go back 10kms to a restaurant they had seen. After leaving the restaurant, they drove 90 more kilometers to Grandma’s house.
1. How many kilometers did the girls drive on the way to Grandma’s house?
2. The time at the stops totaled to 1 hour and 15 minutes. If they were driving at 60km/h and left at 10:30am, what time would they arrive to the Grandma’s house? Answer by ikleyn(52797) (Show Source):
