Answer:
a) 1/7 liters of petrol is used for each mile
Step-by-step explanation:
Justin fills his car with 40 litres of petrol. After travelling 35 miles it's down to 35 litres.
From the above statement:.
The difference is :
40 litres - 35 liters = 5 liters
Hence:
After travelling 35 miles he used 5 liters
(a) How much petrol does the car use each mile?
This is calculated as:
35 miles = 5 Liters
1 mile = x liters
Cross Multiply
35x = 5 Liters
x = 5/35
x = 1/7 liters
Hence, for each mile, 1/7 liters of petrol is used
Answer:
$132.00
Step-by-step explanation:
15 cases at $66; 66 divided by 15= $4.40 a case
20 cases at $88; 88 divided by 20=$4.40 a case
35 cases at $154.00; 154 divided by 35=$4.40 a case
therefore 30 cases x $4.40 per case = $132.00
Answer:
They biked for 1 hour and 38 minutes
Step-by-step explanation:
Here, we want to know the length of the biking time
Mathematically, from the time given;
if they had ended the biking by 2:47
They would have biked for 2 hours
But, as it can be seen, the biking stopped at 2:25 and that is (57-25 = 22 minutes earlier)
So, the length of their biking time would be;
1 hour and (60-22) minutes
and that is 1 hour 38 minutes
