During a trip, Francine traveled x percent of the total distance at an average speed of 40 miles per hour and the rest of the distance at an average speed of 60 miles per hour. In terms of x, what was Francine's average speed for the entire trip

50mph.

Step-by-step explanation:

If Francine's first average speed is 40mph

And her second average sped was measured at 60 mph,

Then her total average speed for the trip would be calculated as

(60 + 40)/2

= 100/2

= 50mph.

Therefore,Francine's initial speed is 40mph,

Her final speed is 60mph,

And her total average speed is 50mph.
