Find the average velocity of a car which travels 360 km in 6 hours, show in m/s and km/h ?

2 Answers

Answer:

Divide the distance by the time you will get average velocity (or more properly: average speed).

Explanation:

#"360 km"/"6 h" = "60 km/h"#

This is equal to #"16.7 m/s"# because

#"60 km" = "60 km" xx "1000 meters"/"1 km" = "60000 meters"#

#"1 hour" = "60 min" xx "60 seconds"/"1 min"= "3600 s"#

So

#"60 km/h" = "60000 m"/"3600 s" = "16.7 m/s"#

Answer:

Average velocity #v = 60# #(km)/h, = 50/3 m / s#

Explanation:

Average velocity (v) = distance travelled (d) / time taken (t).

Given : Distance travelled = 360 km, time taken = 6 hours.

#v = d / t = 360 / 6 = 60# #(km)/h #

#1 km = 1000 m, 1 hour = 60 * 60 = 3600 sec#

#:. v = (60 * 1000) / 3600 = 60 * 5/18 = 50/3 # #m / sec#
