Timmy is on a 2100 mile trip across the country. over the last 12 hours of driving timmy has traveled 720 miles. if he continues traveling at the same rate, how many more hours will it take him to complete his trip? a) 15 hours b) 23 hours c) 35 hours d) 47 hours

B)23 hours

Step-by-step explanation:

distance = rate * time

720 = rate * 12

divide by 12

720/12 = rate*12/12

60 miles per hour = rate

the total distance is 2100

he has completed 720

he has (2100-720) = 1380 miles left to go

distance = rate * time

1380 = 60 * time

divide by 60

1380/60 = time

23 = time

answer: it's d
