Question

A marathon is 26.2 miles. If Sally ran a marathon in 3 hours and 3 minutes, what was her approximate pace?

Answer 1

We have to find Sally's pace . Means, we have to find Sally's speed.

Distance = 26.2 miles
We know, 1 mile = 1.6 km
so, distance in km = 26.2 × 1.6 km = 41.92 km
Time taken , t = 3 hour and 3 minutes
t = (3 + 3/60) hrs = 3 + 1/20 = 3.05 hrs

Now, speed = distance/time taken
= 41.92/3.05 km/hr
= 13.744 km/h

Hence, Sally's pace is 13.744 km/h

Answer 2

Solution:-

Distance = 26.2 miles 

1 mile = 1.60934 km 

= 26.2*1.60934

42.16 km

Time taken = 3 hours 3 minutes

= (3 + 3/60) hours

= (3 + 0.05) hours

= 3.05 hours

Speed = Distance/Time

⇒ 42.16/3.05 

= 13.822 km/hour

So, Sally's approximate pace is 13.822 km/hour
