Starter• The following times are all in hours. Change them into

hours and minutes…

a) 0.5 hoursb) 2.5 hoursc) 3.5 hoursd) 1.25 hourse) 3.75 hours

How would you change 6.71 hours into hours and minutes? Multiply 0.71 (the decimal part) by 60 0.71 x 60 = 42.6

So 6.71 hours is 6 hours and 43 minutes (rounded)

= 30 mins

= 3 hours 45 mins= 1 hour 15 mins

= 3 hours 30 mins= 2 hours 30 mins

StarterHow would you change 6.71 hours into hours and minutes? Multiply 0.71 (the decimal part) by 60 0.71 x 60 = 42.6

So 6.71 hours is 6 hours and 43 minutes (rounded)

Change the following amounts of hours into hours and minutes

a)0.52 hoursb)0.79 hoursc)0.278 hoursd)2.65 hourse)3.12 hours

(0.52 x 60)

= 31.2 mins (31)(0.79 x

60)= 47.4 mins (47)(0.278 x

60)= 16.68 mins (17)

(0.65 x 60) = 2 hrs 39 mins (0.12 x 60) = 3 hrs 7.2 mins (7)

Planning Flights

• Today you will be completing tasks on a range of topics, all of which would be involved in planning an airline route

• We will look at measuring bearings, calculating flight times and from that planning a flight timetable

• We will also need to use scale in order to work out the distances between destinations

Planning FlightsThe flight’s route is from Glasgow to London. We need to fill in the following table:

According to the scale, 4cm = 100 milesThe distance from Glasgow to London = 14cm

14 ÷ 4 = 3.5

(So we need 3.5 lots of 100)

3.5 x 100 = 350 miles

To measure the bearing from Glasgow to London:1)Draw on a line pointing North (just assume the maps are all 2D!)2)Measure the direction from north using a Protractor (you might need to figure out a way to do more than 180°3)Bearings should always be 3-digit numbers. 43 would become 043 for example.

Time = Distance ÷ Speed

(The average speed of a Boeing 747 is around 500mph)

Time = 350 ÷ 500

Time = 0.7 hours

To convert the decimal part to minutes, multiply it by 60 (JUST the decimal part!)

0.7 x 60 = 42 minutes

The flight will need 30 mins for refueling and cleaning. When would be a sensible time to schedule departure?

40 mins 13:50

Allow extra time for delays/waiting for a free

runway etc…

Planning Flights

• We have used a variety of mathematical skills today

• We have seen how pilots use bearings to know which way to travel

• We have also looked at how timetables would be created by considering speed, distance and time
