An airplane went from st. louis to boston. It travels at an average speed of 610km/hr. If the trip takes?

Question

2.75 hours, what is the flight distance between St. Louis and Boston?

Answer 1

well you use the formula

average speed = distance / time

plug in th variables that you know:

610 km/hr = distance / 2.75 hrs

so multiply both sides by 2.75
and you should get

distance = 1677.5 km

Answer 2

Memorize this formula!

(average speed) = distance / time

You can turn it around so it says this:

distance = (average speed) x time

They give you the average speed, and they give you the time. Calculate the distance.
