per second? USE UNIT CANCELLATIONS AND SHOW ALL WORK.

Answer 1

2502 cm/s

Step-by-step explanation:

In conversions from one unit to another,we always use a conversion factor. A conversion factor is a number used to change one set of units to another, by multiplying or dividing. The conversion factor in changing km/hr to cm/s is:

1 km/hr = 27.8 cm/s.

Hence 90 km/hr = 90 * 27.8 = 2502 cm/s
