1 hour after 2.20 p.m. will be 3.20 p.m.

We are then left with 50 minutes to add to the 3.20 p.m.

If you add 40 minutes to the 20 minutes after the 3 p.m. [3.20 p.m.] that will be 1 hour [60 minutes make an 1 hour] and at that time the time will be 4 p.m. [1 hour after 3.00 p.m.] and the 50 minutes will be left with 10 minutes.

10 minutes after 4.00 p.m. is 4.10 p.m.

Hence the match will end at 4.10 p.m.

ALTERNATIVELY

To add time, add the hours separately and the minutes separately

If the minutes is 60 or more, convert to hours and minutes

2.20 p.m. = 2 hours and 20 minutes

Adding 1 hour 50 minutes

Adding Hours

2 + 1 = 3

Adding Minutes

20 minutes + 50 minutes = 70 minutes

60 minutes make an hour, hence 70 minutes is 1 hour 10 minutes

Add the 1 hour to the previous sum of the hours

Total hours = 3 + 1 = 4

Minutes left is 10 minutes

Hence the match ends at 4.10 p.m.

Speed = Distance/Time

Since the unit is metres per second, convert the kilometres to meters and the hour to seconds

Kilo = 1000, kilometres = 1000 metres

36 kilometres = 36 000 metres

60 minutes = 1 hour

1 minute = 60 seconds

60 minutes = 60 x 60 seconds = 3600 seconds = 1 hour

Speed = 36 000m / 3600s = 10 ms^-1

You can make time the subject of the equation

Since time is dividing, you can multiply both sides of the equation by time to cancel the time at the right hand side

Time x Speed = Distance

Divide both sides by Speed

From the question, distance covered = 150 km

Speed was 18 km/h

Time = 150/18

3 goes into 150, 50 times and 18, 6 times

Time = 50/6

2 goes into 50, 25 times and 6, 3 times

Time = 25/3

3 can go into 25, 8 times remainder 1

Time = 8 1⁄3 hours, thus 8 whole number 1 over 3

You can change the fraction part of the hours to minutes by multiplying by 60 minutes. There are 60 minutes in an hour

1⁄3 hours = 1⁄3 x 60 minutes = 20 minutes

Therefore the time taken is 8 hours 20 minutes
