Distance Jack hopped = 50 yards
Distance Jack hopped = 50 x 3 = 150 feet

Distance young kangaroo hopped = 10 feet.

Difference = 150 - 10 = 140 feet

Marysya12 [62]

Answer:

1cm = 50

2 cm = 50 x 2

3cm = 50 x 3

and the inverse:50m = 50/50 = 1cm

100m = 100/50 = 2cm

150m = 150/50 = 3cm

381m = 381/
