Which equation is written correctly in standard form to represent the scenario?

Given that a plane is flyig to metroc city which starts it's journey 1275 miles away from Metro city.

So that means total distance to be travelled by the plane = 1275 miles

We can use formula (distance = speed x time ) to find the distance travelled in each slot.

Given that the plane travels for "a" hours at 550 mph

then distance covered = speed * time = 550*a=550a

Given that the plane travels for "b" hours at 590 mph

then distance covered = speed * time = 590*b=590b

Then total distance travelled = 550a+590b

Given that total distance should be 1275 so both values will be equal

550a+590b=1275

Hence first choice is the final answer.

equal to

step-by-step explanation:

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
