You use the discriminant (b²-sqr(4ac))/2a and if sqr(4ac) inferior to 0 then use i = sqr(-1)
Answer:
10 hours to drive 500 miles
6 hours to drive 300 miles
Step-by-step explanation:
Hi, to answer this we have to calculate the speed rate first:
Speed = distance /time
Speed = 200 miles / 4 hours = 50 miles per hour
So, to find the time for each number of miles:
Time = distance /speed
For 500 miles:
t = 500/50 = 10 hours
For 300 miles
t = 300/50 =6 hours
So, in conclusion:
It will take 10 hours to him drive 500 miles
It will take 6 hours to him drive 300 miles
