   A coach travels 300 km in 5 hours. Work out the average speed in km/h.

   show the answer

   60

   Speed = distance ÷ time = 300 ÷ 5 = 60 km/h.

   A rectangular garden is 8 m long and 6 m wide. Fencing costs £10 per metre. Work out the cost of fencing all four sides of the garden. Give your answer in pounds (£).

   show the answer

   £280

   Perimeter = 2 × (8 + 6) = 28 m. Cost = 28 × £10 = £280.
