Question

A traveler drove 150 miles at 50 miles per hour and then 160 miles at 40 miles per hour. How many hours did the drive take altogether?

Answer 1

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 2

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
