Question

red kangaroo jumps along at 40km/h At this rate how long would it take to jump 2km

Answer 1

40 km = 1hr
2 km = (1*2)/40hrs = 1/20 hrs = (1/20)*60 min = 3 min = 3 * 60 sec = 180 sec

Answer 3

40 km =1 h
2 km = x
x=(2 km* 1h)/40 km =2/40=1/20 h
now 1 h = 60 min
1/20 h =x
x=( 1/20 h * 60 min)/1 h= 60/20=3 min
