A person walks 3 miles in 1 hour, then walks 4 miles in 2 hours. He stops for lunch for one hour to rest. Then he walks 3 miles in 1 more hour. What is his average speed for the journey?
What is the equation for average speed?
A person walks 3 miles in 1 hour, then walks 4 miles in 2 hours. He stops for lunch for one hour to rest. Then he walks 3 miles in 1 more hour. What is his average speed for the journey?
Equation: Save = Dtotal/Ttotal
So we need to find the total distance and total time.
What is the total distance traveled?
A person walks 3 miles in 1 hour, then walks 4 miles in 2 hours. He stops for lunch for one hour to rest. Then he walks 3 miles in 1 more hour. What is his average speed for the journey?
Equation: Save = Dtotal/Ttotal
Dtotal = 10 miles
What is the total time for the journey?
A person walks 3 miles in 1 hour, then walks 4 miles in 2 hours. He stops for lunch for one hour to rest. Then he walks 3 miles in 1 more hour. What is his average speed for the journey?
Equation: Save = Dtotal/Ttotal
Dtotal = 10 miles
Ttotal = 5 hours
Which of the following is correct?
A person walks 3 miles in 1 hour, then walks 4 miles in 2 hours. He stops for lunch for one hour to rest. Then he walks 3 miles in 1 more hour. What is his average speed for the journey?
Equation: Save = Dtotal/Ttotal
Dtotal = 10 miles
Ttotal = 5 hours
Save = 10mi/5hr
Which of the following is correct?
