Answer:
10 hours.
Step-by-step explanation:
Two bicyclists are 200 miles apart when they start racing towards one another.
Their speeds are 12 mph and 6 mph respectively.
Distance = speed × time
Let the time taken by bicyclists = t
We have to calculate the time when they 20 miles apart this means they have covered the distance of 200 - 20 = 180 miles
t(12mph) + t(6mph) = 180
18t = 180
t =
t = 10 hours
It will take 10 hours to both the bicyclists before they are 20 miles apart.
Answer:
C.
Step-by-step explanation:
Let x represent number of miles.
We have been given that a taxi cab charges $1.50 for the flat fee and $0.50 for each mile.
The cost of riding x miles would be and the total cost of riding x miles would be
.
Since Sharon has only $25 to spend on the taxi ride, so the cost of riding x miles on taxi must be less than or equal to 25.
We can represent this information in an inequality as:
Therefore, option C is the correct choice.
