Hello There!

D=Distance

T=Time

S=Speed

For the first one we are given the speed and the time and we need to find the distance

To do so we multiply the two together( the two meaning the speed and the time)

They run 20 m per second and

if they run for 40 second

(20*40=800)

they will run for a total of 800m therefore the answer to the first one is D

for the second one we are given the distance and the time and we need to find the speed.

Looking at the formula chart we can find the speed by dividing the distance over the time

so speed = 80/5

80/5=16 so the speed is 16m/s (B)

For the third one we are given the distance and the time and we need to find the speed

Once again we can find the speed by dividing the distance over time

20/5=4 so the bunny hops 4m/s

For the last one we are given the speed and the distance and we need to find the time it took to get to the associated distance

another way we can find the time is by dividing the given speed by the distance

so time = 1500/250

1500/250=6 so it will take the space ship 6 seconds to reach a distance of 1500m

surface mining destroys mountain tops, landscapes, forests and wildlife habitats. on top of that, it leads to soil erosion and destruction of agricultural land. the landscape changes can also disrupt river channels and streams, which leads to flooding. which, can destroy plant life and other animals as well.
