How much time will Alex need to walk to his school, which is 2 1/4 miles away from his house, if he would walk with the speed of 2 7/10 mph

5/6 hours equivalent to 50 minutes

Step-by-step explanation:

Speed = distance / time

Speed = 2 7/10 miles per hour

Distance = 2 1/4 miles

Time = x hours

Speed = distance / time

2 7/10 = 2 1/4 / x

27/10 = 9/4 / x

Cross product

27/10 * x = 9/4

27/10x = 9/4

Divide both sides by 27/10

x = 9/4 ÷ 27/10

= 9/4 × 10/27

= 1/2 × 5/3

= 5/6 hours

5/6 hours

= 5/6 × 60 minutes

= 50 minutes

Therefore, it will take Alex 5/6 hours equivalent to 50 minutes to walk to his school

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
