Answer: 2.5 hours is the answer
Step-by-step explanation:
It took Travis 2.5 hours to complete 3/4 of his trip. 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

Idk delete this comment I don't deserve it here not a proper answer :(
Ok so if I understand this correctly then you have to find out what each one of them are then add them to get the total number of both of them. So this is the equation I did. The one circled on blue is the formula I made for the equation and then the green one is the answer. which is 5 4/9
I hope this helps.
The answer is -6+x=8. x is the unknown number. To find the distance, try to use a number line. And the answer to the expression is 14. To get from -6 to 0, you add 6. Then from 0 to 8, you add 8. 8+6=14
