first：76 ÷ 19/25=100
a:80 / 20 * 1 / 25 =0.16
b:80 * 5/4 =100
c:80 / 5 ÷ 1 / 4 =64
d:80 * 5/4 =100
e:80 * 4/5 =64
So I think both B and D should be the right answer
20 meter per second= 1200 m/h=1.5km/h
The time is 1300: 1.5 =866.66
Answer:
Step-by-step explanation:

Area of rectangular prism = 2 (lb+bh +hl)
When sides are doubled, Area = 2 (2l * 2b +2b *2h + 2h*2l)
= 4 * 2 (lb+bh +hl)
Volume of rectangular prism = lbh
When sides are doubled, Volume = 2l * 2h * 2b = 8 lbh
