Question

Brainliest!!! We observe that it takes 5,3 seconds to cross the distance of 35
meters. A) What is their average speed? B) How long will it take for
the skier complete the 10,00 km race if they keep the same average
speed?

Answer 1

Answer:

A) speed = distance / time

               =  35 / 5.3

               = 6.6 = 7 m/s

b) 7 m/s = 25.2 km/h = 25 km/h

    speed = distance / time

     time = distance / speed

              = 1000 / 25

              = 4 hrs = 240 min
