Question

The length of a bridge is 230 m. The length of each of Robert's paces is 75 cm.

What is the minimum number of full paces that it would take Robert to walk the full length of the bridge?

Answer 1

307 paces

Explanation:

First, lets convert Robert's pace to metres. (cm > m)

75cm = (75/100)m

= 0.75m

Number of Full Paces = Length of Bridge / 1 Full Pace

=

`(230m)/(0.75m) \\ = 306 (2)/(3) paces`

See , we must have full paces, and in this case we are finding the minimum number of paces, so we will be looking at the lowest possible whole number, which in this case, is 307 paces.
