2.30 PM
Step-by-step explanation:
Olivia has a 1hr head start of Ben. While traveling at 55 mph she will have covered a distance of;
55 * 1 = 55 miles
Then Ben begins to travel at 65 mph which is
65 – 55 = 10 mph
Faster than Olivia.
This means that Ben will be closing in on the 55 miles head-start made by Olivia by 10 mph. To find out after how long Ben will completely close the gap;
55 / 10 = 5.5 hours
0.5 hours in minutes is;
5/10 *60 = 30 minutes
Ben will catch up to Olivia on;
9.00 + 5.30 = 14.30
= 2.30 PM
