Chicago is about 2,800 km from Los Angeles. About how long would it take a jet plane flying 800 km/h to fly from Chicago to Los

BaLLatris [955]

<u>Answer:</u> The time taken by jet plane to reach Los Angeles from Chicago is 3.5 hours

<u>Explanation:</u>

Speed is defined as the rate at which an object moves with respect to time.

To calculate the time taken for the given speed, we use the equation:

$s=\frac{d}{t}$

where,

s = speed of the jet plane = 800 km/hr

d = distance traveled = 2800 km

t = time taken by jet plane = ?

Putting values in above equation, we get:

$800km/hr=\frac{2800km}{t}\\\\t=\frac{2800km}{800km/hr}=3.5hr$

Hence, the time taken by jet plane to reach Los Angeles from Chicago is 3.5 hours
