A plane took 2h 10 minutes to fly from town A(6°S, 70°E) to town B (18°N, 70°E) (Take the radius of the earth to be 6370km
and PI = 22/7 )
a) Find the average speed of the plane.
b) A traveller in the plane spent 30 minutes in town B conducting some business. He took a second plane to town C (18°N,
10°E). The average speed of the second plane was 70% that o the first plane. Determine the time to the nearest minute the
plane took to travel from B to C.
c) When the plane took off at town A the local time was 0400h. Find the local time at C when the traveller arrived .
