Test are not directly used to make measurements, I mean you could use them to put 4 mL of a substance in, but not to measure out 4 mL, like with graduated cylinders. Rulers can be used to measure the length of something, like the number of inches. And a thermometer will help you measure the temperature of something.
<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:

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:

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