Loretta:
Average driving speed = 55 mph
Time = 4 hours
Distance traveled = 55*4 = 220 miles
Dad:
Average driving speed = 65 mph
Let x = hours driven
Distance traveled = 65x miles
The length of the trip is 610 miles, therefore
65x + 220 = 610
65x = 390
x = 6 hours
Answer: Loretta's dad drove for 6 hours.
Answer:
73.25%
Step-by-step explanation:
To solve this, you need to write it as a proportion. The proportion for this problem would be 14.65/20 = x/100. You cross multiply and get 20x=1465. Then you divide both sides by 20 which would mean x=73.25 which is your answer as a percent.
