Answer:
At 50 km/hr, she travels a distance of 40 km
At 100 km/hr, she travels a distance of 160 km
Step-by-step explanation:
The general formula for distance = d = r*t
distance / rate = time
x/50 + y / 100 = 2.4 Multiply by 100
2x + y = 240
x + y = 200
Subtract the two equations
x = 40 km
y = 200 - 40
y = 160 km
Equation- l=65-15d
graph- discrete bc it's only for integer numbers
Use ratio and proportion
5.25/x= 82/100
cross multiply
82 x= 525
x= 6.4 miles
