Question

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.

Answer 1

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.
