Answer:
1 - D
2 - B
3 - A
4 - A
Explanation:
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
