Answer:
See the analysis below
Step-by-step explanation:
Given data
The Carter family
Distance= 285 miles
Time= 4 hours 45 minutes.
Time= 4.75 hours---------converted time to hours
Speed= distance/time
Speed= 285/4.75
Speed= 60 miles per hour
The Hernandez family
Distance=294 miles
Time= 5 hours and 15 minutes.
Time= 5.25hours---------converted time to hours
Speed= distance/time
Speed= 294 / 5.25
Speed= 56 miles per hour
Hence the Carter family is travelling faster at 60 miles per hour
