A car drives at a speed of 500 miles per hour. It takes the car "r" hours to reach its destination. Enter an equation that can be used to find the number of hours it will take the car to 450 miles away

Step-by-step explanation:

v = 500 mi/r hrs

d = vt

t = d/v

t = 450 / (500/r)

t = 450r / 500

t = 0.9r

0.9r

Step-by-step explanation:

Given,

Speed = 500 miles per hour

Time = r hours

Distance = 450 m

So,

Time = Distance/Speed

r = 450/500

r = 9/10

9/10 × r = Time

0.9r = Time
