Kudos for the right answer and explanation
Question part of the project GRE Quantitative Reasoning Daily Challenge - (2021) EDITIONGRE - Math BookGiven: Francis drives 240 miles and then stops (breaks down)
So, Teneka will reach Francis once Teneka drives 240 miles.
How long will it take Teneka to drive 240 miles?Time = distance/speed = (240 miles)/(30 miles per hour) = 8 hours
Teneka started driving at 9:00am
So, after 8 hours, the time will be 5pm
Answer: D
