Question

Jason a 4 lengths of rope. The lengths are 3 inches, 15 centimeters, 0.3 meters, and 0.5 feet. About how much rope does Jason have [1 inch = 2.5 cm]

Answer 1

Answer: 67.5 cm

Step-by-step explanation:

Jason has 4 lengths of ropes

first is $3\ in.\approx 7.5\ cm$

second is $15\ cm$

Third is $0.3\ m\approx 30\ cm\quad [\text{1 m = 100 cm}]$

fourth is $0.5\ ft\approx 6\ in.\approx 15\ cm\quad [\text{1 ft=12 in.}]$

the total length of rope is the sum of four lengths

$\Rightarrow 7.5+15+30+15=67.5\ cm$
