A bicyclist travels the first 1600 m of a trip at an average speed of 8 m/s, travels the next 1200 m in 90 s and spends the last 50 s at a speed of 15 m/s. Find the average speed of the bicyclist for this trip. I will give brainliest whoever answer fastest and most accurate please

13.15m/s

Explanation:

1600÷8=200s

1200÷90=13.33s

50÷15= 3.33s

(1600+1200+50)/(200+13.33+3.33) = 13.15m/s

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west

at right angles to each other
