Answer:
the bus took 4.5 hrs going 60 kph to get from town P to town Q
this means that the distance from town P to town Q is 270 km
side note-the car kph isn't shown and it got to town Q faster than the bus, so it must have gone at a faster speed. i didn't use the car to solve the problem, just the bus.
£1400
A reduction of 40% means that £840 is 60% of the original price
Divide £840 by 60 to find 1% then multiply by 100 to find original price
original price = £840 × 
= £1400
Answer:
[0.184, 0.266]
Step-by-step explanation:
Given:
Number of survey n =280
Number of veterans = 63
Confidence interval = 90%
Computation:
Probability of veterans = 63/280
Probability of veterans =0.225
a=0.1
Z(0.05) = 1.645 (from distribution table)
Confidence interval = 90%
So,
p ± Z*√[p(1-p)/n]
0.225 ± 1.645√(0.225(1-0.225)/280)
[0.184, 0.266]
