2. an airplane travels 335
miles in 45 minutes.
how fast does it travel?
how fast is that in
km/hr?

The answer is 716.8 km/hr

Explanation:

The main idea here is the convert the given units to km and hr. Here's the conversion factors.

1mi= 1.6km

1hr= 60min

We have to multiply 335miles by 1.60km/mi in order to get the answer in km then again we have to multiply 45 minutes by 1hr/60min in order to get the answer in hr.

The last step is to calculate the speed using the formula : v=d/t

=537.6km/0.75hr

=716.8km/hr
