Question

A car traveled 281 miles in 4 hours 41 minutes. What was the average speed of the car in miles per hour?

Answer 1

• 41min=41/60h=0.7h

Total distance=281mi

Total time=4.7h

$\\ \tt\hookrightarrow Avg\:Speed=\dfrac{Total\: distance}{Total\:time}$

$\\ \tt\hookrightarrow Avg\:Speed=\dfrac{281}{4.7}$

$\\ \tt\hookrightarrow Avg\:Speed=59.78mph$

Answer 2

Answer:

= 60 miles / hour

Step-by-step explanation:

We first convert the time of 4 hours 41 minutes in minutes

4 hours 41 minutes = 4 × 60 + 41 = 281 minutes

Average speed S is given by distance / time. Hence

S = 281 miles / 281 minutes = 1 mile / minute

= 60 miles / hour
