Baptist walked 420 m in 17.5 min. what is his average speed in m/min? What is his average speed in m/s? (Hint: There are 60 s in 1 min.)

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

total time taken by it is given as

so average speed is given as

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

so we have

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.

real, smaller and upside-down.   so the answer should be b.
