If the common difference is 3 all you need to do is:
an=a1 - d(n-1)
2 - 3d + 3
Explicit rule = -3n + 5
As there are 60 minutes in an hour the rate per minute is 24/60 = 0.4 km/minute.
Distance travelled in 20 minutes = 20*0.4 = 8 km.
Here is your answer
Area of 2 triangular part
=2× (1/2 × 3 × 4)
=12 sq. units
Area of three rectangular parts= (l×b)
= 11×5 + 11×4 + 11×3
= 55+44+33
= 132 sq. units
Hence,
surface area of prism= 12+132
= 144 sq. units
