Answer:
80
Step-by-step explanation:
If they're travelling towards each other;
Effective speed = 75+55 = 130
Distance = 338m
Time= distance/ speed
T= 338/130
T= 2.6 hrs
Answer: The average distance the ambulance travels to reach an emergency situation is 6.64 miles.
Step-by-step explanation:
Hi, to answer this question we have to apply the speed formula:
Speed rate = distance / time
Replacing with the values given:
0.83 miles per minute = d / 8 minutes
Solving for d (distance)
0.83 mpm x 8 m =d
d =6.64 miles
The average distance the ambulance travels to reach an emergency situation is 6.64 miles.

Answer:
7 - x meters
Step-by-step explanation:
This is a difference of squares. The formula for difference of squares is
a^2-b^2 = (a-b)(a+b)
So plug the numbers we know into this formula.
Area = lw
49 - x^2 = (a-b)(7+x)
49 - x^2 = (7-x)(7+x)
<u>The length is 7 - x meters.</u>
