A truck travels a constant speed of 20m/s . It then decelerates to rest in ten seconds. Find the total distance travelled by the
truck in the 20 seconds.
1 answer:
In the first 10 seconds it is 200m
In the next 10 seconds (it is decelerating 2m/s every second) it is 100m
200m+100m=300m
300 meters is the answer

Yes she will have enough. 4 multiplied by 18 is 72. 72+30=102.
Hope this helped.
1. The mistake is in the second line (didn't fully distribute)
2. The mistake is in the second line (didn't properly add 4p and 7p)
Y=x+5. add 5 to both sides
