Question

QUESTION 1 Which of the following values represents velocity? OA 21.0 mi/h B.12.2 km north ОС 34.1 s O D.56.2 m/s up QUESTION2 The distance from New York to Chicago is 720 mi. Find the time it would take to travel this distance if traveling at 65 mi/h. OA 11 h OB, 0.090 h OC 4.7x 104 h D.660 h QUESTION 3

Answer 1

1) we have to know that units of velocity as km/h, m/s ,mi/h ,yd/s, ft/s etc

therefore the option s with above units are A and D

2.Given data :

distance from newyork to chicago (d) = 720 mi

speed (v) = 65mi/h

therefore time taken (t) = d/v

= 720/65

= 11.07 hours and it is approximately 11 hours

so option A is correct
