a red kangaroo can hop at speeds of 65 km/hr. how much time will it take the kangaroo to hop 0.25 km at that speed?
daser333 [38]

Time = (distance) / (speed)

Time = (0.25 km) / (65 km/hr)

<em>Time = 0.00385 hour</em>

(That's 13.85 seconds.)

<u />

<u>Better way:</u>

Distance = 0.25 km

Distance = 250 meters

Speed = (65 km/hr) x (1000 m/km) x (1 hr/3600 sec)

Speed = 18.06 m/sec

Time = (250 m) / (18.06 m/s)

<em>Time = 13.85 seconds  </em>
