Answer:
4 minutes 3 seconds
Step-by-step explanation:
Step one:
Given data
A kangaroo hops 2 kilometers in 3 minutes
The rate/speed is
rate/speed= 2/3 km per minute
Required
the time taken to cover 3 km
Step two:
We know that
rate= distance/time
2/3= 3/t
cross multiply we have
2t=3*3
2t=9
divide both sides by 2
t= 9/2
t= 4.5 minutes
t= 4 minutes 3 seconds
