Distance = Rate x Time
in this case the distance is the same for both so set
This is my first time here, i really hope that i am in the right section. I have having alot of problems with problem solving, i am in solving problems with rational expressions
This is the question that i have:
Gloria drives a distance of 90 km in 30 min less time than Jayden drives the same distance. What is the speed of each driver if Gloria drives 1.5 times fast than Jayden.
I need to first write an equation for this and then solve. How can i do this?
Let the time it takes Gloria to drive the 90km be , where is measured in mins.
Therefore, the time it takes Jayden is .
Let represent Gloria's speed, and represent Jayden's speed.
Therefore and .
We also know that Gloria's speed is 1.5 times faster than Jayden's.
So
.
So it takes Gloria 60 mins, and Jayden mins.
