Deon plans to ride a 15-mi bicycle trail. if his average speed is 20 mi/h, which equation can he use to find the time t, in hours, for the ride?

The equation would be "t = 15 mile/ 20 miles/hr"

Deon is trying to find out the time that will be taken for the ride:

Time = Distance / Speed

Distance = 15 miles

Speed = 20 miles / hour

Time = 15 / 20

Assuming time is t, the formula would be:

t = 15 / 20

"t = 15 mi/ 20 mi/hr " will help Deon calculate the time he will take.

Relating velocity, distance and time, the equation to find the time t is:

-----------------------

Velocity is distance divided by time, that is:

-----------------------

Replacing into the equation:

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
