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

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72
