Answer:

UV=142

Step-by-step explanation:

21x-13=10x+31

+13 +13

Brady rode his bike 70 miles in 4 hours. He rode at an average speed of 17 miles per hour for t hours and at an average rate of
IceJOKER [234]

Answer:

Brady rides at slower speed which is 17 miles/hours for <em><u>3 hours and 36 minutes.</u></em>

Step-by-step explanation:

Given:

Brady rode 70 miles in 4 hours.

For t hours he rode at the average rate of 17 miles/hour

For rest of the time he rode at the average rate of 22 miles per hour.

To find the time Braady rode at the slower speed.

Solution:

Total time of riding = 4 hours

Time for which Brady rides at 17 miles/ hour = t  hours

Distance covered in t hours = Speed\times time=17\times t =17t\ miles

So, time for which Brady rides at 22 miles/ hour = (4-t) hours

Distance covered in (4-t) hours = Speed\times time=22\times(4-t) =(88-22t)\ miles

Total distance can be given as:

⇒ 17t+88-22t

Simplifying.

⇒ -5t+88

Total distance given =70 miles.

Thus, the equation to find t can be given as:

-5t+88=70

Subtracting both sides by 88.

-5t+88-88=70-88

-5t=-18

Dividing both sides by -5.

\frac{-5t}{-5}=\frac{-18}{-5}

∴ t=3.6 hours

3.6\ hours = 3\ hour+ (0.6\times 60)\ minutes = 3\ hour\ 36\ minutes

Thus, Brady rides at slower speed which is 17 miles/hours for 3 hours and 36 minutes.
