The driving distance between Swansea and London is 198 miles. Ibrahim intends to travel from Swansea to London by coach.
The coach will leave Swansea at 2.30 pm
Ibrahim assumes that the coach will travel at an average speed of 55mph
a) Using his assumption, work out Ibrahim's arrival time in London.

It actually turns out that the coach has a lower average speed.

b) Describe how this affects the arrival time.

part a and b

Step-by-step explanation:

b)It will take him longer to arrive

a)time = distance / speed

198/55 = 3.6  

3 hours and 36 minutes +2:30 = 6:06

518,400

step-by-step explanation:

the area is multiplying all the given measurements together.

40 * 18 * 30 * 24 = 518,400

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
