So car A travels Distance = 60 km/hr*(1+x)
Car B travels Distance = 75 km/hr(x)
Where x is the time in hours.
Those two equations are equal when on overtakes the other
so:
60 +60x = 75x
60=15x
x=4, but my expression is written to count from when car B commenced travel. So total time is 5 hours from the car A setting off.
Answer:
if im correct it should be 40

Answer:
Step-by-step explanation:
Angles 153 and QRP are straight angles, and thus Angle QRP is
180 - 153, or 27 degrees.
The interior angles of the triangle must sum up to 180 degrees:
27 + (3y + 5) + (2y - 7) = 180.
combining like terms, we get:
5y - 25 = 180, or 5y = 155, or y = 31
Then Angle Q is 3(31) + 5, or 93
Angle P is 2(31) - 7, or 55, and
Angle QRP is 27 degrees (found earlier).
The equation that represents profit is $40x - $20.
The profit after 5 days in business is $180.
The profit after 10 days in business is $380.
The profit after 10 days in business if revenue is $45 is $430.
<h3>What is profit? </h3>
Profit is total revenue less total cost.
Profit = total revenue - total cost
Profit = $40x - $20
Where:
x = number of days
<h3>What is the total profit after 5 days and 10 days? </h3>
$40(5) - $20
= $200 - $20
= $180
$40(10) - $20
$400 - $20
$380
<h3>What is total profit if revenue is $45? </h3>
$45(10) - $20
= $450 - $20
= $430

Answer:
60 km/hr
Step-by-step explanation:
Speed = distance / time
Speed = 360 km / 6 hr
Speed = 60 km/hr
