Answer:
The panther will run 120 km in 90 mins
Explanation:
An hour is 60 mins and you know in 1 hour the panther can run 80km
all you need to do is figure out how many miles an xtra 30 mins will be
60 minutes divided by 2 = 30 minutes and 80 km divided by 2 = 40km
Therefore 30 minutes = 40km
just add this to the original statement and you're good
60 mins + 30 mins = 90 mins
80km + 40km = 120km
The panther will run 120km in 90 mins
