Divide 150 by 50 to get that that part of the drive took 3 hours. Then divide 160 by 40 to get that that part of the drive took 4 hours. Therefore, the whole trip took 7 hours.

Answer:

7 hours

Explanation:

Hello

in physics, velocity is the physical magnitude that shows and expresses the variation in terms of position of an object and as a function of time


V=(s)/(t) \\\\

where, V is velocity, s is the distance and t is the time

isolating time(t)


V=(s)/(t) \\\\\\\\V*t=s\\\\t=(s)/(V)


t_(1)=(150\ miles)/(50(mi)/(h) )\\t_(1)=3\ hours\\\\t_(2)=(160\ miles)/(40(mi)/(h) )\\t_(1)=4\ hours\\\\the\ total\ time\ he\ drove\\\\t_(1)+t_(2)=3\ h + 4\ h\\\\total\ time = 7\ hours

Have a great day
