Question

The length of a bridge is 190 m. The length of each of Robert's paces is 80 cm.
What is the minimum number of full paces that it would take Robert to walk the full length of the bridge?

Answer 1

Answer:

Step-by-step explanation:

Length of the bridge = 190 m = 190*100 = 19000 cm    {100cm = 1m}

Length of each pace of Robert = 80 cm

Minimum number of full paces = 19000/80

=  237.5

= 238   {because full paces}

Answer 2

Answer:

238 paces

Step-by-step explanation:

190 m : 80 cm =

= 190×100cm : 80cm

= 19000cm : 80cm

= 237.5 paces

≈ 238 paces
