Question

Jim drove 455 miles in 7 hours.
At the same rate, how many miles would he drive in 5 hours?

Answer 1

Jim would drive 325 miles in 5 hours at the same rate of travel.

Step-by-step explanation:

Jim drove 455 miles in 7 hours. To find out how many miles he would drive in 5 hours, we need to calculate his average speed and then use it to estimate the distance for the 5-hour journey.

Step 1: Calculate the average speed in miles per hour.
Average speed = distance ∕ time = 455 miles ∕ 7 hours = 65 miles per hour.

Step 2: Determine the distance Jim would drive in 5 hours at the same rate.
Distance in 5 hours = average speed × time = 65 miles per hour × 5 hours = 325 miles.

Thus, at the same rate, Jim would drive 325 miles in 5 hours.

Answer 2

Given parameters:

Distance covered = 455 miles

Time taken = 7 hours

New time taken = 5 hours

Unknown:

New distance = ?

To solve this problem, we need to define what speed entails.

Speed is a physical quantity and it is distance divided by time.

Speed =
`(distance)/(time )`

In this problem, we first find the rate at which Jim is driving;

Speed =
`(455)/(7)` = 65miles/hr

Now that we know the rate, we can simply find the new distance;

New distance = speed x new time taken

Input the parameters;

New distance = 65miles/hr x 5hrs = 325miles
