Charlotte drove a total of 329.5 miles on a two-part road trip. In the first part of the trip, she drove for 2.5 hours. In the second part of the trip, she drove an average of 9 miles per hour faster, and drove for 3 hours. What was Charlotte's average speed over each leg of the trip? You can use a table to organize the quantities (speed, time, and distance) for each leg of Charlotte's trip. If we let z represent Charlotte's average speed for the first leg (in miles per hour), then her average speed over the second leg is x +9 miles per hour. Organize data with a table Rate X Time = Distance first leg of trip 2.5 second leg of trip x+9 3 According to the table, the total distance that Charlotte traveled is miles. Now set up and solve an equation to find Charlotte's average speeds. Charlotte had an average speed of miles per hour over the first leg of the trip. Charlotte had an average speed of miles per hour over the second leg of the trip.

confused on how to solve this , i know how to put the data in the table but unsure how to find the rest

Charlotte drove a total of 329.5 miles on a two-part road trip. In the first part of the trip, she drove for 2.5 hours. In the second part of the trip,
she drove an average of 9 miles per hour faster, and drove for 3 hours. What was Charlotte's average speed over each leg of the trip?
You can use a table to organize the quantities (speed, time, and distance) for each leg of Charlotte's trip. If we let x represent Charlotte's
average speed for the first leg (in miles per hour), then her average speed over the second leg is x +9 miles per hour.
Organize data with a table
Rate
X Time = Distance
first leg of trip
2.5
second leg of trip x + 9
miles.
According to the table, the total distance that Charlotte traveled is
Now set up and solve an equation to find Charlotte's average speeds.
Charlotte had an average speed of
miles per hour over the first leg of the trip.
Charlotte had an average speed of
miles per hour over the second leg of the trip.
