You need to first use the formula of calculating surface area of a cuboid
SA=2(lw+lh+wh)
now you put the values in as
H=3
W=1.5
L=2.5
You get 31.5
Hope this Helps!
E is the answer I am pretty sure.
Answer:
1 hour
Step-by-step explanation:
Hello, let's say that her departure trip takes t in minutes, as her return speed is 3 times her departure speed, she took t/3 for the return and we know that this 40 minutes less, so we can write.
t/3=t-40
We can multiply by 3
t = 3t -40*3 = 3t - 120
This is equivalent to
3t -120 = t
We subtract t
2t-120 = 0
2t = 120
We divide by 2
t = 120/2 = 60
So this is 60 minutes = 1 hour.
Thank you.
