The average speed is 615.7 mph (275.2 m/s)
Explanation:
The average speed of an object gives a measure of how fast an object is moving over a certain time interval. It is a scalar quantity, and it is calculated as follows
where
v is the average speed
d is the distance covered
t is the time interval
For the jet in this problem, we have:
d = 1293 mi is the distance covered
t = 2.1 h is the time interval
Therefore, the average speed is:
We can also convert into SI units (m/s), keeping in mind that:
And so
