Question

Travis lives 196 miles Dallas.On a normal trip it would take 180 minutes to drive from his house to Dallas. What is the average rate of speed in miles per hour.

Answer 1

The average rate of speed is 65.33 miles per hour.

Explanation:

Total Distance = 196 miles

Time required = 180 minutes.

Now time is given in minutes we need to convert in hours.

60 minutes = 1 hours

180 minutes = number of hours in 180 mins

By using Unitary method we get;

Number of hours in 180 mins =
`(180)/(60)=3 \ hrs`

Hence Time taken = 3 hrs

We need to find the speed.

Speed can be calculate by dividing Total distance with Time taken to travel the distance.

Speed =
`(Distance)/(Time)=(196)/(3)= 65.33\ miles \ per\ hour`

Hence the average rate of speed is 65.33 miles per hour.
