75416 ft/min

(857 mi/h) x (5280 ft/h ÷ 1 mi / 1h ) x (1h x 1 ft ÷ 60 min x 1 ft)

Explanation:

Conversion of 857 mi/h to feet /second.

We'll begin by converting 857 mi/h to ft/h.

This is illustrated below:

Recall:

1 mi/h = 5280 ft/h

Therefore,

857 mi/h = 857 x 5280 = 4524960 ft/h

857 mi/h = 4524960 ft/h

Finally, we shall convert 4524960 ft/h to ft/min.

This can be obtained as follow:

Recall:

1 ft/h = 1/60 ft/min

Therefore,

4524960 ft/h = 4524960 x 1/60 = 75416 ft/min

4524960 ft/h = 75416 ft/min

Therefore, 857 mi/h is equivalent to 75416 ft/min.

To solve the above question in a shorter for we simply do the following:

(857 mi/h) x (5280 ft/h ÷ 1 mi/1h ) x (1h x 1 ft ÷ 60 min x 1 ft)

it's all four options.

the answer to this question is 3.
