B) 2.5 hours , because 8 mph is 1 hour and the another 8mph is 1 hour 8+8mph =16mph 1+1hr=2hr half of 8 is 4mph is .5hr so therefore 8+8+4=20mph 1+1+ 30mins= 2.5hr
Roger: $24
Bethan: $36
Explanation:
4/5 of $75 is $60
So $60 is distributed to Roger and Bethan in the ratio 2 : 3.
Add the numbers in the ratio 2 : 3
2 + 3 = 5
Divide $60 by 5
60 ÷ 5 = 12
Multiply each number in the ratio 2 : 3 by 12:
2 • 12 : 3 • 12
= 24 : 36

Answer:
The greatest possible error for the measurement 3.2 cm is 0.05 cm.

To find : What is the greatest possible error?
Solution :
The greatest possible error in a measurement is half of the measuring unit.
Measurement 3.2 cm.
