Answer:
A. 3 hours 20 minutes
Step-by-step explanation:
The distance divided by the speed gives you the time.
(234 miles)/(70 mph) = 3.343 hours.
3.343 hours is decimal hours. We need hours and minutes.
1 hour = 60 minutes. We separate the whole hours from the decimal part of the hours, and we multiply the decimal part of the hours by 60 to find minutes.
3.343 hours =
= 3 hours + 0.343 hours
= 3 hours + 0.343 hours * 60 minutes/hour =
= 3 hours + 20.6 minutes
The closest answer is:
A. 3 hours 20 minutes
£3.99 divided by 8 is £0.49875
Which, changed into pence and rounded up, is 50p.
£2.79 divided by 6 is £0.465
Which, changed into pence and rounded up is 47p.

50 subtract 47 is 3p
The second one has the better value for money as it costs 3p less per battery.
N - 1 = 1st number
n = middle number
n + 1 = 3rd number
(n - 1) + n + (n + 1) = 3n <== ur expression
