Emily drives her car 293.8 km with a
constant speed of
82 km/h and another
194.4 km with a
constant speed of
48 km/h. How much
time in total does she
take to travel these
distances?

Since there is already an answer i will try to go more into depth about how it was solved.

Explanation:

Using the basic equation S=d/t, where S is speed is in km/hr, d is distance in km, and t is time in hours, we can plug in the two separate pairs of known variables.

Pair 1:

S=d/t

82km/hr=293.8km/t

t=3.583hr

Pair 2:

S=d/t

48km/hr=194.4km/t

t=4.05hr

since the question is asking us for the total time, we can add these two together.

3.583hr+4.050hr=7.633hr

So she has traveled for a total of 7.633 hours

Hope this helps you understand the question a little more!
