Awoman drives a car from one city to another with different constant speeds along the trip. she drives at a speed of 80.0 km/h for 25.0 min, 65.0 km/h for 20.0 min, makes a stop for 60.0 min, then continues at 40.0 km/h for 30.0 min, at which point she reaches her destination.

Total distance traveled= 75.36km (point at which she reaches her destination.)

Explanation:

With the speed and time data we can calculate the distance traveled on each path, but first we must transform the time units from minutes to hours:

First ride:

v=80km/h     t=25min*1h/60min=0.42h

distancie= v*t = 80km/h * 0.42h =33.6km

Second ride:

v=65.0km/h   t= 20min*1h/60min= 0.33h

distance= 65.0km/h*0.33h=21.67km

Stop: 60min= 1h  distance=0km

third ride:

v= 40.0km/h   t= 30.0min *1h/60min= 0.5h

distance= 40.0km/h*0.5h=20km

Total distance traveled= 33.6km +21.76km+20km

Total distance traveled= 75.36km

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this

the answer is c. the lower legs are levers, and the knees are fulcrums. the ankles hold the loads.
