Answer 1

Distance divided by time gives average speed. Find average speed?

Distance is 281 miles. Time is 4 hours 41 minutes, or 281 minutes.

Distance divided by time gives average speed. 281 miles per 281 minutes.

1 mile per 1 minute. Or 60 miles per hour. 60 mph.

Answer 2

Answer:

Given :-

• A car traveled 281 miles in 4 hours 41 minutes.

To Find :-

• What is the average speed of the car in miles per hour.

Formula Used :-

$\clubsuit$ Average Speed :

$\longmapsto \sf\boxed{\bold{\pink{Average\: Speed =\: \dfrac{Total\: Distance}{Total\: Time}}}}$

Solution :-

First, we have to convert the minutes in to hours :

$\implies \sf Time =\: \dfrac{\cancel{41}}{\cancel{60}}$

$\implies \sf\bold{\green{Time =\: 0.683\: hour}}$

Hence, the total time will be,

$\implies \sf Total\: Time =\: 4\: hours + 0.683\: hours$

$\implies \sf\bold{\purple{Total\: Time =\: 4.683\: hours}}$

Now, we have to find the average speed of the car,

Given :

• Total distance = 281 miles
• Total time = 4.683 hours

According to the question by using the formula we get,

$\implies \sf Average\: Speed =\: \dfrac{281}{4.683}$

$\implies \sf Average\: Speed =\: \dfrac{281}{\dfrac{4683}{1000}}$

$\implies \sf Average\: Speed =\: 281 \times \dfrac{1000}{4683}$

$\implies \sf Average\: Speed =\: \dfrac{281000}{4683}$

$\implies \sf\bold{\red{Average\: Speed =\: 60.004\: miles/hours}}$

$\therefore$ The average speed of the car in miles per hour is 60.004 miles/hours.
