103.737 m

23.96 degrees south of west

average speed = total distance traveled divided by 7 = (60+75+30)/7 165/7 = 23. 4/7 mph

average velocity = the displacement/7 = 103.737/7 = 14.820 m/s 23.96 degrees south of west

It helps to draw a diagram. If he's going south and then makes a right, he's then going west

the driver went 60 m south, then 75 west, then 30 northwest. That's a total mileage of 165 m in 7 minutes, an average speed of 165/7 = 23.571 m per minute or 7 4/7 m per min.'

draw the displacement on a diagram, connect the starting point to the finishing point

calculate that distance. it's the hypotenuse of a right triangle with sides 60-15sqr2 and 75+15sq2

Use the distance formula, h^2 = (60-15sqr2)^2 + (75+15sqr2)^2 h=103.737 approximately.

or h^2 = 96.213^ + 38.787^2 expand, solve for h = the displacement, = distance from start to finish as the crow flies.

which one(s) were incorrect?06/01/21

Raymond B.

Hmm, after punching the numbers in a calculator again, I revised the numbers, slightly. Is the problem asking for a specific number of decimal places?06/01/21

Raymond B.

or does it want the exact answer in radical form?06/01/21

Hello Mr. Raymond B, Kindly please, are you sure this is right sir? I have put that answer in my homework and it claims it is incorrect.06/01/21
