these are the only 2 questions i don't get:
-how long would it take for a car to travel a distance of 200 km if it is travaling at a velocity of 55 km/hr?
is the answer 4hrs and 3 min.?
-an an carries food at a speed of 1 cm/s.how long will it take the ant to carry a cookie crumb from the kitchen table to the ant hill,a distance of 50m? express ur answer in seconds,minutes,andhours
i didn't get that one at all
Thank You very much!!! :)
