Sally rides her bike to the store to get some Skittles. The store is 5 km away. If it takes her 10 minutes to get to the store what is her average
speed?

0.5 km/hr
0.5 mph
0.5 km/min
5 km/min

Sally's average speed is 0.5 km/min

Explanation:

speed=distance/time

so, 5km/10min=0.5 km/min

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.

i believe the answer is 5,000
