Question

You leave on a 546-mi trip in order to attend a meeting that will start 10. 8 h after you begin your trip. Along the way you plan to stop for dinner. If the fastest you can safely drive is 65 mi/h, what is the longest time you can spend over dinner and still arrive just in time for the meeting?.

Answer 1

2,48 hours

100% correct...........

Answer 2

Step-by-step explanation:

To find the time the driver can stop for, we must calculate the time it takes him to complete the trip without any stops:

Time without stops =
`(546 miles)/(65miles/hour) = 8.32 hours` (approximated)

Since the driver has 10.8 hours to complete the journey, thus the driver can stop for 10.8hrs - 8.32hrs = 2.48hrs
