After 270 seconds, both cars will meet again at the startingpoint.
To find the time at which both cars meet again at the starting point, we need to find the least common multiple (LCM) of their lap times. The LCM is the smallest positive integer that is divisible by both lap times.
David's car lap time = 90 seconds
Chris' car lap time = 54 seconds
Now, let's calculate the LCM:
Find the prime factors of each lap time:
90 = 2 × 3² × 5
54 = 2 × 3³
Take the highest power of each prime factor:
LCM = 2 × 3³ × 5
= 2 × 27 × 5
= 270 seconds
So, after 270 seconds, both cars will meet again at the startingpoint.

Answer:
h
Step-by-step explanation:
Answer:
54 miles in one hour.
Step-by-step explanation:
A car travels in 3 hours = 162 miles
We have to calculate the speed of car in one hour.
Therefore, we use the formula of speed =
=
= 54 miles/hour
The car travels 54 miles in one hour.
-The rays and the angle have two endpoints each.
-The rays and the angle have their lines extending in opposite directions.
-The rays have a number of points lying on them and the angle has only one point lying on it.
-The rays extend infinitely and the angle is made by the rays which have a common endpoint.
...?
Answer:
-The rays extend infinitely and the angle is made by the rays which have a common endpoint.
Step-by-step explanation:
A ray starts from one point and extends in one direction forever.
An angle is the space between two intersecting lines at or close to the point where they meet. In this case two rays intersect each other at one point

D. -30 + d
The shortest distance from a point to a straight line is the measurement of the line segment which connects the point to the straight line. This line segment should be perpendicular to the line and is thus called the perpendicular distance.
