Question

You travel 20.0 mph for 0.500 hour, 40.0 mph for 1.00 hour, 30.0 mph for 0.500 hour, and 50.0 mph for 2.00 hours. What is the total distance traveled?

Answer 1

Speed is
`(distance)/(time)`, so because you already know the time(.5 + 1 + .5 + 2 = 4 hours), you want to find the distance traveled.

`(Speed)/(time) = ((distance)/(time))/(time)=(distance)/((time)/(time))=distance`
So you set it up like this:

`(20mph)/(.5\ hour)= 10 miles \\ (40mph)/(1\ hour)= 40 miles\\ (30mph)/(.5\ hour)= 15miles\\ (50mph)/(2\ hours)=100miles \\ Add\ them:\\ 10+40+15+100=165miles`
You traveled 165 miles total.
