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

t = 15 / 20

Step-by-step explanation:

Given:

Distance traveled by Deon to ride a bicycle trail = 15 mile

Average speed of Deon to ride a bicycle trail = 20 mi/hour

Step-by-Step:

Let 'T' be the time taken to ride the bicycle trail.

We will use distance speed formula to write the equation to find the time 'T' in hours, for the ride.

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.

Therefore, t = 15 / 20

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
