Cyclist A leaves point X at 12 noon and travels at constant velocity in a straight path. Cyclist B leaves point X at 2 p.m. trav

fredd [130]

Answer:

37.5 miles per hour

Step-by-step explanation:

The question might be trying to confuse the reader. Point (1) which states the difference in weight does not show any evidence on how it affects the speed of both cyclist. Point (2) show an important point where the distance traveled is 75 miles.

Cyclist B, who leave point X at 2pm overtook cyclist A at 4pm, showing that the time it took for B to overtook A is 2 hours

Speed = distance / time

= 75 miles / 2 hours

= 37.5 miles per hour

On a map, the distance between two towns is 3.4 inches. The map scale is 2 inches: 25 miles. What is the actual distance between

Mariulka [41]

For this question we can solve it by setting up a proportion:

$\frac{2inches}{25 miles}= \frac{3.4inches}{x}$

Now we can solve for x to find the total distance between the towns. Let's cross multiply and solve for x:

$2x=85$
$x=42.5miles$

So now we know that the total distance between the towns is 42.5 miles.
