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

Respuesta :

Answer:

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

Number of hours required to cover 450miles is (9/10)hours.

What is speed?

" Speed is defined as the rate at which total distance covered by an object."

Formula used

Speed = (Total distance covered) / (time taken)

According to the question,

Given,

Speed = 500miles per hour

Time taken = 'r' hours

Distance travelled= 450miles

Substitute the value in the formula we get,

  500 = 450 / r

⇒ r = (450 / 500)

⇒ r = (9 /10) hours

Hence, number of hours required to cover 450miles is (9/10)hours.
