Answer:

lower bound = 90 - 10 = 80 cm

upper bound = 90 + 10 = 100 cm

lower bound d = 1500 x 80 cm = 120,000 cm

upper bound d = 1500 x 100 cm = 150,000 cm

Distance of upper bond and lower bond is 120,000 and 150,000 centimeter

Given:

Number of steps walk = 1500 steps

Each step count = 90 centimetres

Correction in each step = 10 cm nearset

Find:

Lower bound and upper bound for d

Computation:

Lower bound step length = 90 - 10

Lower bound step length = 80 centimetres

Upper bound step length = 90 + 10

Upper bound step length = 100 centimetres

Lower bound d = 1500 × 80

Lower bound d = 120,000 centimetres

Upper bound d = 1500 × 100

Upper bound d = 150,000 centimetres
