Answer:
It take 20 minutes to run 4 kilometres
Step-by-step explanation:
As we run 6 kilometres in 30 minutes
Equation is 4×30÷6=20
Then each 1kilometre take 5 minutes
The quadratic formula is used for finding the axis of symmetry of the parabola.

As "x" increases by 1, "y" increses by 5
.
Answer: D x > -2
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Recall your d = rt, distance = rate * time
the buses are traveling in opposite directions, but both are taking off at the same time
let's say bus A is going at 63mph and bus B is going at 62mph, so, we know their "r" rate for each
ok, after they had travelled for "t" time, they're both 187.5 miles apart, at that instant, bus A has been travelling for "t" hours and bus B has been also travelling for "t" hours as well
now, if bus A covered say "d" miles in those "t" hours, then bus B covered the slack from 187.5 and "d", or 187.5 - d
thus
solve for "t".
