Question

A jet travels 1000 kilometers in 5 hours. What is its average speed?

Answer 1

Given:

Total distance = 1000 kilometer

Total time = 5 hours

To find:

Average speed = ?

Formula used:

$v_{avg}$ = $\frac{s}{t}$

Where $v_{avg}$ = average speed

s = total distance

t = total time

Solution:

Average speed of the jet is given by,

$v_{avg}$ = $\frac{s}{t}$

Where $v_{avg}$ = average speed

s = total distance

t = total time

$v_{avg}$ = $\frac{1000}{5}$

$v_{avg}$ = 200 km/ h

Thus, average speed of the jet is 200 km/h.

Hence, Option (A) is correct.
