Ava and kelly ran a road race,starting at the same time and same place.Ava ran at an average speed of 6 miles per hour.Kelly ran at an average speed of 8 miles per hour.If kelly finished the race in 1 1/2 hour.How long did it take Ava to finish the race
Da = Dk = 6*T = 8*1.5
T = 2 h.
t
To find out how long it took Ava to finish the race, we can use the formula:
time = distance / speed
First, let's find the distance of the race. Since both Ava and Kelly started at the same time and place, they must have covered the same distance.
Since Kelly finished the race in 1 1/2 hours (which is 1.5 hours), let's use her time to find the distance.
distance = speed * time
distance = 8 mph * 1.5 hours
distance = 12 miles
So, the distance of the race is 12 miles.
Now, let's find the time it took Ava to finish the race using the distance and her average speed.
time = distance / speed
time = 12 miles / 6 mph
time = 2 hours
Therefore, it took Ava 2 hours to finish the race.
