Question

If a little old lady is doing 98.3 kilometers/hour, will she get a speeding ticket if the speed limit is 55 miles / hour? [USE: 5280 feet = 1 mile and 2.54 cm = 1.00 inch] (Show how to convert to miles / hour, even if your calculator does it for you.)

Answer 1

It is possible she could get one.

Step-by-step explanation:

To solve this problem we need to convert 98.3 kilometers/hour to miles/hour.

In other words, we convert km to mi, to do so we multiply 98.3 km by a conversion factor, putting the unit we want to have in the numerator, and the unit we want to convert in the denominator:

• 98.3 km *
  `(1000m)/(1km) *(100cm)/(1m)*(1in)/(2.54cm) *(1ft)/(12in) *(1mi)/(5280ft)` = 61 mi

Given that the little old lady is doing 61 miles/hour, she could get a speeding ticket.
