TASK 4: Read the text and answer the following questions.
It is a computer drawing of the plane of the future. British engineers and
scientists have published plans for a new hypersonic plane called the A2. It
will be very fast. At the moment, a flight from London in the UK to Sydney
in Australia takes about twenty-one hours but with the A2 the same flight
will take around four hours.
The flight will fly at 4,500 kilometres per hour and will fly at an altitude
of over 10,000 metres.
It will carry 300 passengers but it don't have any windows because scientists
haven't found glass that is strong enough. It will be better for the
environment than other planes because the engines won't produce gases that
cause pollution.
In the future, will people travel from London to Australia for the
weekend? It's possible! Both how much will a ticket cost? The planners say
that it won't be very expensive - about £2,000. The A2 will be ready for its
first flight in 2020.
How long does it take the A2 plane to fly from London to Sydney?
What is the speed of the plane?
What is the altitude of the flight?
How many passengers can it carry?
How much does a ticket for the flight from London to Sydney cost?
