Answer:
1 : 5000
Step-by-step explanation:
Firstly align the unit
Map 5cm represent 250m = 250x100cm = 25000cm
scale = 5 : 25000 = 1 : 5000
Convert feet to miles. 1 mile = 5280 feet 607200/5280 = 115 607, 200 feet per hour = 115 miles per hour
Answer:
1) if he wants to do that he needs 0.6 gallons x 14 days = 8,4 gallons.
If the car starts with 14 gallons then he is able to ride 14 days without the warning light.
2) now he would need 0.6 gallons x 25 days = 15 gallons.
he only has 14 gallons so that is not possible.
3) no clue sorry
4) x= the days he can drive without the warning light
14-1,5 = 0,6.x
<=>12,5= 0,6.x
<=>20,833... = x
He can go 20 days without the warning light.
5) x= the days he can drive his car without seeing the warning light.
x.0,6<12,5
<=> x<20,833...
If he drives 20,833... days he will see the warning light so everything before that he won't see it.
