To find the average speed, we need to find his speed during 3/4 of the trip and then the 52.5 miles.
So you know that 52.5 is 1/4 of his total trip. That means if we multiply that by 3, that's how many miles he traveled in 2.5hrs. (157.5)
To calculate speed, divide distance by time.
For 3/4 of his trip (157.5), it took him 2.5 hours.
157.5/2.5 = 63mph
For the remaining 52.5 miles, it took him an hour.
52.5/1 = 52.5mph
Now average those two speeds to get the average speed for the whole trip.
(63+52.5)/2= 57.6mph
Answer: 12 bowls
Step-by-step explanation:
Divide: 8 : 2 /3= 8/ 1 · 3/2= (8 · 3 / 1 · 2) = 24/2 =12
To divide one fraction by another, invert (turn upside-down) the second fraction, then multiply.
8 : (2/3) = 12/ 1= 12
