Charlie runs at a speed of 3 yards per second . about how many miles per hour does charlie run?

6.14 miles/hour

Step-by-step explanation:

Charlie runs at a speed of 3 yards per second.

First we have to calculate the speed per hour in yards.

1 hour = 3600 seconds

In one second Charlie runs = 3 yards

in 3600 seconds he runs = 3600 × 3

                                          = 10,800 yards

Since 1760 yards = 1 mile

Hence, 10,800 yards =

                                   = 6.13636 ≈ 6.14 miles

Charlie runs at the speed of 6.14 miles per hour.
