Answer:
hours per day
Step-by-step explanation:
Given,
Distance = 192 miles
Rate = 9.6 miles per hour
Lets find her total time of riding by using Distance Formula ( D = RT ).
D = RT
192 = 9.6T
T = 192/9.6
T = 20 hours
Total time she needs to meet goals is 20 hours.
There are 7 days in a week and she plans to ride same hours each day, so that will be:
20/7 hours per day
28+8=8+10+p
36=18+p
Subtract 18 on the left and right hand side
36-18=18-18+p
p=18
T= # of rental hours
Multiply number of hours rented by the cost per hour, add that total to the reservation fee. The total needs to be less than $91.
Reservation + ($ per hr * # hrs) < $91
$19 + $6t < $91
subtract 19 from both sides
6t < 72
divide both sides by 6
t < 12
ANSWER: To spend less than $91, they need to rent the room less than 12 hours.
Hope this helps! :)
