# If a runner ran 6.2 miles in 34 minutes, what was his average speed in mph?

Relevance
• Speed = Distance/Time

s = 6.2 miles/34 minutes

s = 6.2 miles/34 minutes (60min/2hr)

s = 10.941176470588235 mi/hr

Now round to 2 digits

s = 11 mph

Never answer with more digits than given.

• 6.2*60/34=10.94118 mi/h.

• That's impossible

• If a runner ran 6.2 miles in 34 minutes,

his average speed was

6.2(60/34) = 372/34 = 10 16/17 mph.

• thats impossible

• You are given miles and minutes. So convert minutes to hours. Now you have miles and hours. What does per mean in math terms?

• Distance Divided by Time (in hours) = Miles Per Hour.

34 minutes = 0.5667 hours

6.2 / 0.5667 = 10.94 Miles per hour (rounded = 11 Miles per hour)

• formula

average speed = distance / time

34 minutes = 34/60 hours

• 6.2 x 60/34 = 10.9 mph.

1 hour = 60 minutes. 6.2/34 =x/60---- They taught us Dimensional Analysis in nursing school. It's excruciating to learn (far easier to just shoot yourself in the gonads so you can skip school), but it's so simple and workable that Dora The Explora could do it.  https://en.wikipedia.org/wiki/Dimensional_analysis
