Question

Mary passed a certain gas station on a highway while traveling west at a constant speed of 50 miles per hour. Then, 15 minutes later, Paul passed the same gas station while traveling west at a constant speed of 60 miles per hour. If both drivers maintained their speeds and both remained on the highway for at least 2 hours, how long after he passed the gas station did Paul catch up with Mary?A. 30 min

B. 45 min
C. 1 hr
D. 1 hr 15 min
E. 1 hr 30 min

Answer 1

d

Explanation:

Distance traveled = (time)(speed)

= (1/4)(50)

= 50/4

= 12.5 miles

Time = (distance)/(speed)

= 12.5/10

= 1.25 hours
