Answer:
201miles
Explanation:
Distance = speed x time
With this formula we will obtain the other formulas to solve the problem
In this case the variable that changes is the speed, the distance remains constant and is the incoginite , but FIRST, we must known the time he has been traveling.
then for the first case
Distance = 60mph x time
and for the second case
Distance = 50mph x (time + 40mintues)
40 minutes= 0,67 hours
matching the two equations
Distance = Distance
60mph x time = 50mph x (time + 0,67hours)
60mphTime = 50mphTIme + 33,5mph
10mphTime = 33,5mph
Time = 33,5mph / 10mph
Time = 3,35 hours
In the first equation
DIstance = 60mph x 3,35 hours
Distance = 201 miles
in equation 2
Distance = 50mph x (3,35 hours + 0,67hours)
Distance = 201miles
I would say D, but to be safe you should wait until someone else awnser she and then compare.
