Answer:
x=3 and 1/2
Step-by-step explanation:
4x+7y=-14
8x+5y=8
2(4x+7y=-14)
8x+14y=-28
8x+5y=8
9y=-36
y=-4
8x+5(-4)=8
8x-20=8
8x=28
x=3 and 1/2
Answer:
Distance=Speed×Time
When speed is 40 kmph
Distance traveled by car =40×9
=360 km
When speed is 60 kmph
Time taken to complete the journey =
60
360
=6 hours
The answer is 25 miles per day.
one mile = 8 furlongs
fortnight = 2 weeks = 14 days
convert furlongs to miles;
2800/8 = 350 miles
it means you travel 350 miles in 14 days
miles per day = 350/14 = 25
Thus, you travel 25 miles per day.
