Explanation
Step 1: Divide the number of flights cancelled in Gatwick by the total number of cancelled flights across the 3 airports in February:
20 / (15+20+45) x 100
= 25%
Explanation
Step 1: Calculate the number of flights cancelled in November and December:
Nov + Dec = 15 + 10 = 25
Step 2: Calculate the number of flights cancelled in January and February:
Jan + Feb = 35 + 45 = 80
Step 3: Subtract the Jan / Feb figure from the Nov / Dec figure and divide by the Nov / Dec figure:
(80 - 25) ÷ 25 x 100 = 220%
Explanation
Step 1 – Calculate the Time taken for the 2 train journeys between London and Manchester:
07:50 train: 2 hours 15 mins = 2.250 hours
10:30 train: 2 hours 25 mins = 2.417 hours
Step 2 – put figures into the formula: Average speed = Distance / Time taken
Average speed = 164 miles / Time taken = miles per hour
07:50 train: 164 miles / 2.250 = 72.9 mph
10:30 train: 164 miles / 2.417 = 67.9 mph
Difference between the two = 72.9 - 67.9 = 5mph
Thus the correct answer is, 5 mph
Explanation
Step 1: The question asks for the ratio of the flights canceled at Gatwick airport vs the other airports combined. Start by writing them down in a ratio format:
20 : (30 + 20 + 15)
20: 65
Step 2: Divide 65 by 20 to calculate the ratio:
65 ÷ 20 = 3.25
1: 3.25
Explanation
Step 1 – Calculate the time taken for each of the coach journeys that serves breakfast.
Departures:
06:30 and 08:00 take 3 hrs 15 mins;
09:10 and 09:30 departures take 3 hours 20 mins;
10:00 departure takes 3 hours and 5 mins
Step 2 – Calculate the total cost for two return tickets
10:00 departure; 2 x £85
Thus the correct answer is, £170
Explanation
Step 1 – Work backward from the taxi journey
Agent must leave Manchester’s coach/train station by coach/train
Step 2 – Which coach/train travel option(s) arrives before 12:25/12:35 respectively?
The 09:10 and 09:30 coach departures both arrive too late
The 09:20 train departure arrives in time at 11:50 and is cheaper than the 9.00 train, Thus the correct answer is, the 09:20 train departure
Explanation
Step 1: Take the number of flights canceled in January and calculate an 80% reduction:
30 × (1-0.8) = 6
Step 2: Subtract this figure from the March figure:
10 - 6 = 4
