Question 906785
Assuming that kangaroos hop at 63.0 km/hr, divide the distance by the rate of speed: 0.27/63.0 to get 0.0042857142857 of an hour.  Multiply that by 60 to get minutes: 0.257152847.  Multiply that by 60 to get seconds: 15.42857 seconds.  May be approximate, due to rounding.  How many places do you need to take it?<br>You could also do it by finding out how far a kangaroo travels in a second.  Divide 63.0 by 3600 (3600 seconds in an hour) to get 0.0175 km per second.  Divide .27/0.0175 to get 15.42857 seconds.
