A person takes a trip, driving with a constant

speed 98.5 km/h except for a 20.8 min rest

stop.

If the person's average speed is 61 km/h,

how much time is spent on the trip?

Answer in units of h.

For this problem, we are asked to calculate for the distance traveled. We set up the equations as follows:

Distance = 61 km/hr * (time + 20.8/60 s) Distance = 98.5 km/hr * time

We equate the two equations, then we can solve for the time spent on the trip. Hope this answers the question. Have a nice day.
