Question

A bird flies at a top speed of 20,000 meters per hour.

he bird flies 30,000 meters without stopping.
For how many hours did the bird fly if it flew at top speed?
In part (a), did you rewrite a formula to find the number of hours
the bird flew, or did you use another approach? Explain.

Answer 1

To calculate the time the bird flew, we used the formula time = distance/speed. By applying the bird's top speed of 20,000 meters per hour and a distance of 30,000 meters, we determined that the bird flew for 1.5 hours.

Step-by-step explanation:

To determine the number of hours the bird flew, we need to use the formula which relates speed, distance, and time. The formula we can use is time = distance/speed. If a bird flies at a top speed of 20,000 meters per hour and flies 30,000 meters without stopping, we can calculate the time as follows:

First, we establish the bird's speed: 20,000 meters per hour.

Next, we find out the total distance flown by the bird: 30,000 meters.

To calculate the time, we divide the total distance by the speed: time = 30,000 meters / 20,000 meters per hour.

So, the time taken by the bird to fly 30,000 meters at top speed is 1.5 hours.

This is a direct application of the formula for time, which does not require the formula to be rewritten, but rather inputting the known values for distance and speed to solve for the unknown variable, time.
