Question

How many minutes would it take a car to travel 42 miles at a

constant speed of 56 miles per hour?

Answer 1

To travel 42 miles at a constant speed of 56 miles per hour, it would take the car 45 minutes.

Step-by-step explanation:

To find the time it would take for a car to travel 42 miles at a constant speed of 56 miles per hour, we can use the formula:

Time = Distance / Speed

Plugging in the values, we get:

Time = 42 miles / 56 miles per hour = 0.75 hours

Since there are 60 minutes in an hour, we can convert the time from hours to minutes by multiplying by 60:

0.75 hours * 60 minutes per hour = 45 minutes

Therefore, it would take the car 45 minutes to travel 42 miles at a constant speed of 56 miles per hour.

Answer 2

45 minutes.

Step-by-step explanation:

We can imagine this as a percentage equation;

`(42)/(56) =(x)/(100)`

`(4200)/(56)=75`

42 is 75% of 56, so if a car is traveling at 56 miles an hour, it travels 42 miles in only 75% of the time. 75% of an hour is 3/4 of 60 seconds, which is:

`60((3)/(4))\\ 180/4=45`

The car will take 45 minutes to travel 42 miles at 56 mph.
