Samir begins riding his bike at a rate of 6 mph. Twelve minutes later, Chris leaves from the same point and bikes along the same
kakasveta [241]

<u>Answer:</u>

The correct answer option is 24 min.

<u>Step-by-step explanation:</u>

Let  us assume t to be Chris's time (in hours)  so we can write the following equation:

Samir's time (in hours)  =t + \frac{12}{60} = t + 0.2

Chris's rate  (r_1)=9 mph

Samir's rate  (r_2)=6 mph

Then putting the values in the formula to get:

r_1t = r_2(t + 0.2)

9t = 6(t + 0.2)

9t=6(t+0.2)\\\\9t=6t+1.2\\\\9t-6t=1.2\\\\3t=1.2\\\\t=0.4

<em>t = 0.4 </em>which will be 0.4*60=24

Therefore, Chris catches up Samir after riding for 24 minutes.

The are of the triangle below is 9/20 square centimeters. What’s is the length of the base? Express your answer as a fraction in
umka21 [38]

Answer:

6/5

Step-by-step explanation:

For this you need to clear the formula for the area which is bxh/2=A, now you need to clear the base and the formula would be b=Ax2/h, and would be (9/20)x2/ 3/4 equal to 18/20 / 3/4 and gives the result of 72/60,now you need to simplify and the simplest form is 6/5
