Answer:

Average speed is 24 m/min

in another unit is is 0.4 m/s

Explanation:

As we know that the average speed is the ratio of total distance covered and total time

so here we know that total distance moved by the baptist is

$d = 420 m$

total time taken by it is given as

$t = 17.5 min$

so average speed is given as

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

$v = \frac{420}{17.5} m/min$

$v = 24 m/min$

now we have to find the speed in m/s unit also

so we have

$v = \frac{24}{60} m/s$

$v = 0.4 m/s$
